Click on &quot;new job&quot; and then select &quot;Copy existing job&quot; at the bottom. Then enter the name of the job you want to copy into the text field.

In addition to copying a job, I sometimes copy parts of the XML file that contains the job configuration. You just paste the copied part into the xml file of the new job and reload the configuration (under *manage hudson*). This is helpful when you change the original job after you created your copy. However, for your use case the copy is the right thing to do.

When you do new job, you can make the choice to copy it from an existing job. Later alter the settings of the new job.

[Note: This question had the original title &quot;__C (ish) style union in C#__&quot;
but as Jeff&#39;s comment informed me, apparently this structure is called a &#39;discriminated union&#39;]


Excuse the verbosity of this question.

There are a couple of similar sounding questions to mine already in SO but they seem to concentrate on the memory saving benefits of the union or using it for interop.
[Here is an example of such a question][1].

My desire to have a union type thing is somewhat different.

I am writing some code at the moment which generates objects that look a bit like this

    public class ValueWrapper
    {
        public DateTime ValueCreationDate;
        // ... other meta data about the value

        public object ValueA;
        public object ValueB;
    }

Pretty complicated stuff I think you will agree.  The thing is that `ValueA` can only be of a few certain types (let&#39;s say `string`, `int` and `Foo` (which is a class) and `ValueB` can be another small set of types.  I don&#39;t like treating these values as objects (I want the warm snugly feeling of coding with a bit of type safety).  

So I thought about writing a trivial little wrapper class to express the fact that ValueA logically is a reference to a particular type.  I called the class `Union` because what I am trying to achieve reminded me of the union concept in C.


    public class Union&lt;A, B, C&gt;
    {
        private readonly Type type; 
        public readonly A a;
        public readonly B b;
        public readonly C c;

        public A A{get {return a;}}
        public B B{get {return b;}}
        public C C{get {return c;}}

        public Union(A a)
        {
            type = typeof(A);
            this.a = a;
        }

        public Union(B b)
        {
            type = typeof(B);
            this.b = b;
        }

        public Union(C c)
        {
            type = typeof(C);
            this.c = c;
        }

        /// &lt;summary&gt;
        /// Returns true if the union contains a value of type T
        /// &lt;/summary&gt;
        /// &lt;remarks&gt;The type of T must exactly match the type&lt;/remarks&gt;
        public bool Is&lt;T&gt;()
        {
            return typeof(T) == type;
        }

        /// &lt;summary&gt;
        /// Returns the union value cast to the given type.
        /// &lt;/summary&gt;
        /// &lt;remarks&gt;If the type of T does not exactly match either X or Y, then the value &lt;c&gt;default(T)&lt;/c&gt; is returned.&lt;/remarks&gt;
        public T As&lt;T&gt;()
        {
            if(Is&lt;A&gt;())
            {
                return (T)(object)a;    // Is this boxing and unboxing unavoidable if I want the union to hold value types and reference types? 
                //return (T)x;          // This will not compile: Error = &quot;Cannot cast expression of type &#39;X&#39; to &#39;T&#39;.&quot;
            }

            if(Is&lt;B&gt;())
            {
                return (T)(object)b; 
            }

            if(Is&lt;C&gt;())
            {
                return (T)(object)c; 
            }

            return default(T);
        }
    }


Using this class ValueWrapper now looks like this

    public class ValueWrapper2
    {
        public DateTime ValueCreationDate;
        public  Union&lt;int, string, Foo&gt; ValueA;
        public  Union&lt;double, Bar, Foo&gt; ValueB;
    }

which is something like what I wanted to achieve but I am missing one fairly crucial element - that is compiler enforced type checking when calling the Is and As functions as the following code demonstrates

        public void DoSomething()
        {
            if(ValueA.Is&lt;string&gt;())
            {
                var s = ValueA.As&lt;string&gt;();
                // .... do somethng
            }

            if(ValueA.Is&lt;char&gt;()) // I would really like this to be a compile error
            {
                char c = ValueA.As&lt;char&gt;();
            }
        }


IMO It is not valid to ask ValueA if it is a `char` since its definition clearly says it is not - this is a programming error and I would like the compiler to pick up on this.  [Also if I could get this correct then (hopefully) I would get intellisense too - which would be a boon.]  

In order to achieve this I would want to tell the compiler that the type `T` can be one of A, B or C

        public bool Is&lt;T&gt;() where T : A 
                               or T : B // Yes I know this is not legal!
                               or T : C 
        {
            return typeof(T) == type;
        } 

Does anyone have any idea if what I want to achieve is possible?  Or am I just plain stupid for writing this class in the first place?

Thanks in advance.

I have Hudson as continuous integration server and I want to use option &#39;Publish JUnit test result report&#39;. But I don&#39;t use xUnit tools for testing, instead of that i have shell scripts which run tests and return results in simple format. I am thinking to make a script which transforms these results to the JUnit format. So i&#39;m interesting how the JUnit file must look?

What is the JUnit XML format specification that Hudson supports?

I&#39;m trying to do a find and replace over many files within an Eclipse project, but I can&#39;t seem to find a way to do it.

(It seems to be a pretty basic task; it&#39;s surprising me that I can&#39;t find a way to do it.)

I have a C# solution with two projects: a service (the main project) and a logger. The service uses classes from the logger. I&#39;ve added a Reference to the logger project within the service project. At design time, autocomplete works fine: the logger&#39;s classes are visible, references that I use are colored appropriately.

I Rebuild the solution, and things go wrong. The references are no longer recognized: &quot;The name &#39;Logging&#39; does not exist in the current context&#39; and the classes no longer exist in autocomplete. Removing and reattaching the reference gets me back to the base state of having the identifiers visible to autocomplete.

I&#39;ve rebooted, cleared all caches, made sure this is the only instance of VS 2010 running on my machine.

Is there something obvious (obviously) that I&#39;m missing?

Task is to form Visual Studio 2010 project so, that during any build or publish some `foo.exe` utility should be copied to output (`bin`) directory.  

Early I have made PostBuildEvent task in .csproj (MSBuild-file):

    &lt;PropertyGroup&gt;
      &lt;PostBuildEvent&gt;
        Copy &quot;$(SolutionDir)Tools\foo.exe&quot; &quot;$(ProjectDir)$(OutDir)foo.exe&quot;
      &lt;/PostBuildEvent&gt;
    &lt;/PropertyGroup&gt;
 

But this is not universal. During publishing (Visual Studio 2010) `foo.exe` appears in `bin` directory, but is not copied to output publish directory. Maybe I do everything completely wrong and there is standard mechanism to include files in projects to be later, during build or publish, copied to `bin`?

I&#39;ve installed NetBeans 6.9.1 and installed few updates for it.

Then I&#39;ve created a new project from existing sources. After a few changes I&#39;ve closed it. And now I am having an error, when trying to open a new project from existing sources (the same files):

&gt; Sources directory is already netbeans project (maybe only in memory).

After Googling it, I noticed it happened not only with me. But I didn&#39;t find the correct solution. I&#39;ve tried to restart the IDE, I&#39;ve tried to restart the PC, I&#39;ve tried to reinstall NetBeans. Nothing helped.

As I was writing up this question I managed to solve it so repeat it here for the benefit of others. Here is the initial problem:

I have created a very simple library project which I want to reference in another project. I have done this previously with no problems so not really sure why it is not working this time. I have:

 1. Flagged the library project via project properties. The `default.properties` file has this set : `android.library=true`

 2. In my other project added reference to my library project via project properties. The `default.properties` file has the reference added as expected ie `android.library.reference.1=K:/android_test_ws/applicationRegistrar`

 3. The green tick against the referenced library project starts off green and then changes to a red cross.

This implies that there must be something wrong / missing from the library project but I don&#39;t know what. My library project on this occasion is MUCH simpler than the previous one I created.

How do you tag your release versions in git?

Now I have each release identified by build number, but they increment even if there are no changes in the repo. My idea is to have it generated automatically on successful deployment on staging server. E.g.

- run Hudson build
- when successful, add new tag, i.e. 1.0-1
- on next *successful* build add next tag, 1.0-2
- version tag is displayed then in site footer

This would require:

- Hudson to manage next version numbers
- or script to store last tag in some file
- or parse git tags to determine last

Any tips?

I using ant exec task to execute xcodebuild  to build some iOS projects hudson. I would like to be able to crate script that way that allows not to specify sdk version, because after updating sdk on hudson slave or my iOS projects all my projects failing....

There is is nice option in xcode since sdk 4.2 in target setup `Base SDK - Latest iOS`

and I don&#39;t have to provide `-sdk` param in xcodebuild command, but then (i think) it&#39;s taken from xcode project and it&#39;s bad because then some one can  change target from simulator to device accidentally during commit.

I need something that is constant. I will prefer not to use env variable because I would like to be able to run this ant task also on dev machines and would like not have to renember about setting it on all machines.

Unfortunately `xcodebuild -showsdks` gives only:

    Mac OS X SDKs:
    	Mac OS X 10.4                 	-sdk macosx10.4
    	Mac OS X 10.5                 	-sdk macosx10.5
    	Mac OS X 10.6                 	-sdk macosx10.6
    
    iOS SDKs:
    	iOS 4.2                       	-sdk iphoneos4.2
    
    iOS Simulator SDKs:
    	Simulator - iOS 3.2           	-sdk iphonesimulator3.2
    	Simulator - iOS 4.0           	-sdk iphonesimulator4.0
    	Simulator - iOS 4.1           	-sdk iphonesimulator4.1
    	Simulator - iOS 4.2           	-sdk iphonesimulator4.2

 

I need something like `-sdk iphoneosLatest`. My only idea is to pare output of `xcodebuild -showsdks` with some script, but I don&#39;t like this idea.

parameter for xcodebuild for using latest sdk.

Anyone out there have experience with both Hudson and Bamboo? Any thoughts on the relative strengths and weaknesses of these products?

Okay, since folks keep mentioning other CI products I&#39;ll open this up further. Here are my general problem. I want to setup a CI system for a new project.  This project will likely have Java components (WARs and JARs), some python modules, and possibly even a .NET component. So I want a CI server that can:

 1. Handle multiple languages,
 2. Deploy artifacts to servers (i.e. deploy the war if all the unit tests pass.)
 3. I would also like something that integrated with a decent code coverage tool. 
 4. Good looking reports are nice, but not essential.
 5. Multiple notification mechanisms when things go wrong. 
 6. I&#39;m not worried about hosting. I&#39;ll either run it on a local server or on an Amazon instance. 
 7. Also, this maybe pie in the sky, but is there something that can also build iPhone apps?
