To get Eclipse to not flag the `@SuppressWarnings(&quot;PMD&quot;)` annotation, look under the menu headings Java -&gt; Compiler -&gt; Errors/Warnings -&gt; Annotations -&gt; Unhandled Token in &#39;@SuppressWarnings&#39; and set it to ignore.

Right on the [PMD][1] page.

I am trying to create a multiline Textbox using ASP.NET MVC with the following code.

    &lt;%= Html.TextBox(&quot;Body&quot;, null, new { TextBoxMode = &quot;MultiLine&quot;, Columns = &quot;55px&quot;, Rows = &quot;10px&quot; })%&gt;

It just shows up a single line fixed sized textbox. 

on the other hand 

    &lt;asp:TextBox runat=&quot;server&quot; ID=&quot;Body&quot; TextMode=&quot;MultiLine&quot; Columns=&quot;55&quot; Rows=&quot;10&quot;&gt;&lt;/asp:TextBox&gt; 

renders the right view, but in the controller&#39;s post method with formCollection named form 

    form[&quot;Body&quot;]; 

returns a null value.

It seems there are different ways to do joins using linq. One is more straightforward and involves just joining tables like this:

    var found = from c in s.categories
                join cm in s.categorymaps on c.CategoryId equals cm.ChildCategoryId
                select c;

There is another way using lambdas and I&#39;m having a heck of a time trying to figure out how to join using this syntax. Can anyone provide links to detailed explanations and lots of examples? Or just simply demonstrate using examples how to use this rather confusing syntax?

    var x = _session.All&lt;category&gt;().Join&lt;categorymap,category, ....

I need to use `System.exit(0)` in an application. Eclipse has the PMD plugin installed and complains about this line of code. Adding `@SuppressWarnings (&quot;PMD.DoNotCallSystemExit&quot;)` remove that warning but now I get a warning that this `SuppressWarnings` is unsupported, despite the fact that it works. 

Is there a way to resolve this?

I am currently trying to develop an application for Android in the latest release of Eclipse. When I try to build and run, the following comes up: 


    [2011-02-17 17:08:03 - &lt;ProgramName&gt;] The connection to adb is down, and a severe error has occured.
    [2011-02-17 17:08:03 - &lt;ProgramName&gt;] You must restart adb and Eclipse.
    [2011-02-17 17:08:03 - &lt;ProgramName&gt;] Please ensure that adb is correctly located at &#39;C:\&lt;sdk-directory&gt;s\platform-tools\adb.exe&#39; and can be executed.

Now, I have updated the ADT plugin, I have the latest version of the Android SDK; adb.exe is, in fact, in the platform-tools directory and can be executed. I&#39;ve tried everything I found on Google:

 - I tried adb kill-server and adb start-server
 - I tried to run it with an without an emulator started
 - I have the given directory in my PATH (I tried with just the platform-tools in the path and I tried with having both platform-tools and tools in my PATH).

Notes: I am running Windows 7. Also, I have previously tested apps in Eclipse. This error is new to me since upgrading the SDK.

Is there any way to completely turn Eclipse to a dark IDE?
Here&#39;s a [Picture][1] of what I&#39;m asking:

I don&#39;t mind doing 1 hour of work to do something like this :D


**EDIT:**

As Konstantin Komissarchik said, I had to modify my OS colors. This is possible by adding a custom Visual Style to the Windows. With the aid of a [Custom Theme](http://www.eclipsecolorthemes.org/) and a [Custom Visual Style for Windows 7](http://jaycee13.deviantart.com/art/Mango-XB-K-Visual-Style-7-244943275) (Which I have changed a little bit), my Eclipse looks like the picture below:
![Screenshot of my Eclipse][2]

## Update 2019:

The latest versions of Eclipse now come with a dark theme. Just go to `Window -&gt; Preferences -&gt; General -&gt; Appearance -&gt; Theme` and select &quot;Dark&quot; or another appropriate version based on your operating system.

[![Eclipse default dark theme][3]][3]

Of course you can still enable dark visual styles to your Windows or change your theme on other operating systems but the default dark theme is good enough for the most part.

I&#39;m getting the following error when I try to run a simple JSP program on Tomcat in Eclipse. 

&gt; Several ports (8005, 8080, 8009) required by Tomcat v6.0 Server at localhost are already in use. The server may already be running in another process, or a system process may be using the port. To start this server you will need to stop the other process or change the port number(s).

How is this caused and how can I solve it?

We are working on a web project from scratch and are looking at the following static code analysis tools.

 - Conventions (Checkstyle)
 - Bad practices (PMD) 
 - Potential bugs (FindBugs)

The project is built on Maven. Instead of using multiple tools for the purpose, I was looking at a single flexible solution and came across SonarQube.

Is it true that we can achieve the results from Checkstyle, PMD and Findbugs with SonarQube? 

Is SonarQube Replacement for Checkstyle, PMD, FindBugs?

In my application, I am running my code through PMD.It shows me this message:

&gt; -            Avoid printStackTrace(); use a logger call instead. 

What does that mean?

I have a big maven project that uses the pmd plugin for code quality checks.

since I started using the pmd plugin i get the following warning message:

    [WARNING] Unable to locate Source XRef to link to - DISABLED

I googled and found that i need to implement the jxr plugin.

so I add the following to the build property in the main pom.xml file.

&lt;!-- language: lang-xml --&gt;

      &lt;plugin&gt;
        &lt;groupId&gt;org.apache.maven.plugins&lt;/groupId&gt;
        &lt;artifactId&gt;maven-jxr-plugin&lt;/artifactId&gt;
        &lt;version&gt;2.3&lt;/version&gt;
      &lt;/plugin&gt;

welp it doesn&#39;t really change anything. 

any ideas what I need to implement in order to resolve this warning message?

Unable to locate Source XRef to link to

I wold like to disable particular warnings for all files that are included, directly or indirectly, by particular include files. For example, I want to disable the warning &quot;you are assigning a string literal to a char*&quot;, for all files or files included by files included by a `#include &lt;bar/*&gt;` (the star in my case means &quot;anything may be here&quot;). 

The reason is, some of the people I have to program with just can&#39;t use &quot;const&quot;, so in the end I get lots of warnings about that particular string literal abuse. I would like to ignore those thousands of warnings coming from their code, so I can concentrate on the mistakes in my own code and fix them. 

I use Intel C++ and GCC. Some of my buddies use clang, so I would be glad to hear solutions for that too. 

How to disable warnings for particular include files?

We use reflection extensively to set class field values in our code. The fields are accessed in code but they are never assigned except via reflection. So IDEA displays &quot;is never assigned&quot; warning. If I ask IDEA to suppress the inspection, it inserts

    @SuppressWarnings({&quot;UnusedDeclaration&quot;})

but this also disables the check of whether the field is used or not, which we do not want.

Is it anyhow possible to disable only &quot;not assigned&quot; check and leave &quot;not used&quot; check for specific fields only?

IDEA version is 10.5

I have imported the three20 project into my project, and when I upgraded to Xcode 4.2 with iOS 5, a bunch of warnings appeared in the project.  

I don&#39;t care about them, but they make a lot of noise, and it&#39;s easy to miss any real warnings in my project now.  Is there a way to disable warnings for those specific libraries?

Disable warnings in Xcode from frameworks

I have a package in R (ROCR) that I need to load in my R environment.  Upon loading the package, a set of messages are printed.  This is ordinarily fine, but since the output of my R script is being used for further analysis I want to completely disable all of this output.  How do I do that?  Furthermore, I&#39;d prefer to do it without having to modify ROCR at all, so that future users of this script don&#39;t have to do that either.

So far:

 - `sink()` doesn&#39;t work here - redirecting both stdout and std err to `/dev/null` does nothing for me.
 - Unsurprisingly, `options(warnings=-1)` does nothing either, since these are not warnings, per se, being printed.

Any thoughts?

Disable messages upon loading a package

I know this question is common and asked many times on Stack Overflow, but after visiting nearly the four pages of search engine results and nearly the 20 question of Stack Overflow regarding this issue, I found that none of them is resolved or answered correctly.

**What I want:**

I want to show my app in recent apps list when it is running but when I close app then my process should be killed and application should be removed from recent apps list.

**Some answers I found:**

    use System.exit(0); //doesn&#39;t clear app from recents
    OR
    use android.os.Process.killProcess(android.os.Process.myPid()); //doesn&#39;t clear app from recents
    OR
    use finish() or this.finish() or Activity.finish();// doesn&#39;t clear app from recents

And one common suggestion I see in every answer that add below code in manifest:

    android:excludeFromRecents //I think this is wrong approach.

because after adding this when user presses home button while my app is running then user cannot see my app in recent Apps List.

And many other suggestions on this but none of them do both tasks close application and clear application from recent apps list. Also if you go in `Settings&gt;Apps&gt;yourApp&gt;your Application` see that still it asks for &quot;force stop&quot; means application is running!
