I receive the following warning:

    [javac] build.xml:9: warning: &#39;includeantruntime&#39; was not set, 
    defaulting to build.sysclasspath=last; set to false for repeatable builds

What does this mean?

I want to setup the Android dev environment from command line, and encounter the following issue:

    wget http://dl.google.com/android/android-sdk_r22.0.5-linux.tgz

after extract the file, run

    tools/android update sdk --no-ui

However, it is too slow on running

    Fetching https://dl-ssl.google.com/android/repository/addons_list-2.xml

The result is that nothing in folder build-tools, and I want is aapt and apkbuilder, since I want to build apk from command line without ant.


How to install Android SDK Build Tools on the command line?

Historically, this has been done with the [Microsoft Build Tools][1]. But it seems that [the Build Tools may not be available for versions after 2015][2]. The replacement appears to be the Visual Studio build tools, which doesn&#39;t seem to have a real homepage yet.

I downloaded the [VS2017 Professional installer][3], and went to the **Individual Components** tab. Right away, the summary is telling me that the Visual Studio core editor is there, taking up 753MB. I don&#39;t want the editor. Just msbuild. There is no way to unselect the editor.

Is there a way I can install the latest version of msbuild without also installing the Visual Studio IDE?

Google just [open-sourced](https://github.com/bazelbuild/bazel) its build tool [Bazel](https://bazel.build/). What are the differences between this tool and [Gradle](https://gradle.org/)? What can it do that Gradle cannot, what does it do better, and what does Gradle do better?

I have installed Rust on windows from [Rust installation page][1]. After installation I tried running the &quot;hello world&quot; program but got the following error.

Is there a way to build tests with SBT without running them?

My own use case is to run static analysis on the test code by using a scalac plugin. Another possible use case is to run some or all of the test code using a separate runner than the one built into SBT.

Ideally there would be a solution to this problem that applies to any SBT project. For example, Maven has a test-compile command that can be used just to compile the tests without running them. It would be great if SBT had the same thing.

Less ideal, but still very helpful, would be solutions that involve modifying the project&#39;s build files.

I cant seem to get build tools for the latest gradle at all. I suspect its something to do with proxy setting for gradle. I have had a good look online but still cant seem to find a solution. I use gradle 2.1.

I created gradle.properties file in my /home/user/.gradle folder with these setting.

&gt; systemProp.http.proxyHost=proxy 
&gt; systemProp.http.proxyPort=80
&gt; systemProp.http.proxyUser=myusername
&gt; systemProp.http.proxyPassword=password
&gt; 
&gt; systemProp.https.proxyHost=proxy 
&gt; systemProp.https.proxyPort=80
&gt; systemProp.https.proxyUser=myusername
&gt; systemProp.https.proxyPassword=password

Here is my global **build.gradle**

    buildscript {
        repositories {
            mavenLocal()
            mavenCentral()
        }
    
        dependencies {
            classpath &#39;com.android.tools.build:gradle:0.13.0&#39;
            classpath fileTree(dir: &#39;build-libs&#39;, include: &#39;*.jar&#39;)
        }
    }
    
    
    allprojects {
        repositories {
            mavenCentral()
        }
    }

And here is the error i get when running `gradlew`

```

What am I missing? that maven link opens fine in a browser.

Out of memory issue after updating buildToolsVersion &#39;23.0.1&#39; in Android studio

I am trying out npm as a build tool.
 
One stumbling block I have encountered is that I need to copy javascript files from one folder to another. The source folder contains typescript files, javascript files and map files, but in the target folder I am only interested in javascript files. 

I do not want to make a copy-statement for each file, but would like to copy all .js files. Also, my source folder contains subfolders that also contains javascript files. These need to be copied as well, and maintain the subfolder structure.

What I have tried is using [NCP][1] with a filter, but I cannot get the filter to work. I have tested the regex used in the filter and it appears to work fine. The test was done at [Regex Tester][2] with regular expression `.*\.js$` and test-strings like `main.ts`, `main.js` `main.js.map` etc, and only the .js strings were matched.

My package json contains the following (abbreviated):

    {
        &quot;scripts&quot;: {
            &quot;copy&quot;: &quot;ncp scripts wwwroot/scripts --filter=\&quot;.*(\\\\.js$)\&quot;&quot; 
        }, 
        &quot;devDependencies&quot;: { 
            &quot;ncp&quot;: &quot;2.0.0.0&quot; 
        }
    }
Since my regex is in a string in a string I have double-escaped it. I have also tried other variations, for example:

    --filter=/.*\.js$/g       - compilation error
    --filter=/.*\\.js$/g      - no files copied
    --filter=\&quot;.*\\.js$\&quot;     - no files copied
    --filter=\&quot;/.*\\.js$/g\&quot;  - no files copied
    (no filter)               - all files copied

I am in no way married to NCP. If something else works better then I will use that.

So: How do I, inside package.json&#39;s scripts section copy only files with a speific extension to another folder? I am pretty sure I have overlooked something blindingly obvious...

I have 2 flavors, lets say Vanilla and Chocolate. I also have Debug and Release build types, and I need Vanilla Release to have a field true, while the other 3 combinations should be false.

    def BOOLEAN = &quot;boolean&quot;
    def VARIABLE = &quot;VARIABLE&quot;
    def TRUE = &quot;true&quot;
    def FALSE = &quot;false&quot;

        VANILLA {

            debug {

                buildConfigField BOOLEAN, VARIABLE, FALSE

            }

            release {

                buildConfigField BOOLEAN, VARIABLE, TRUE

            }


        }

        CHOCOLATE {
            buildConfigField BOOLEAN, VARIABLE, FALSE
        }


I&#39;m having an error, so I guess the debug and release trick doesnt work. It is possible to do this?

I had some warnings saying:

I fixed those, but there are 6 more in the appcompat-v7 library.

If I revert the build tools version to 20 everything works fine.

Has anyone came across this problem?

Android Gradle Project upgrading build tools to 21.0.1: aapt throws Exception

I&#180;m running a linux android sdk installation and my new project needs Build tools 21.1.1


Somehow, this build tools do not exist, eventhough my sdk is up to date, but in the build-tools folder there is now android-4.4W folder

android update sdk --no-ui

![enter image description here][1]

My sdk/build-tools folder

I&#180;ve moved the content testwise to a 21.1.1 folder, but this isn&#180;t recognized either.

Is this a bug?How to I get the right build tools?
