Debuging of jar contents in Intellij Idea - maven

I have a non-trivial maven build which produces a jar fille and I want Itellij Idea to pick up maven's output and then launch the jar but IDE doesn't allow me to specify a jar to use in 'Application' launch configuration. Please suggest a way to configure project this way.
Thanks in advance

You can create a new dummy module with this jar added to its Dependencies and attach sources to the library, then you can debug it by specifying the main class in the Run configuration. The module itself may not contain sources or other content roots.

Does maven care about file names?

I am trying to install some dependencies using maven in a spring boot project.
I am looking for a jar
org.apache.maven.plugins:maven-resources-plugin:jar:3.1.0
But I wanna know if the jar file should have this name maven-resources-plugin, or if the file name is not important for maven. I mean if maven will automatically know which jar file should use.
I will appreciate any help or feedback.
That is a plugin, not a dependency as such (meaning that Maven needs it for building your project, your code doesn't need it to compile or run).
You should only have to specify the plugins groupId, artifactId and version plus any configuration in your pom.xml, and Maven knows exactly what jar to get and how to use it.
See https://maven.apache.org/plugins/maven-resources-plugin/plugin-info.html for further information.

How to create non-executable jar with dependencies? (multi-module)

how are the pom settings for create a non-executable jar-with-dependencies? (multi-module)
I can‘t find anything working
The Maven shade plugin can help. When configuring the plugin, you can control the contents of the manifest, thus making the jar non-executable. A sample configuration is provided here.

Maven: generate MANIFEST in custom location

I am trying to retrieve the implementation title and version for a maven jar module. If I use Myclass.class.getPackage().getImplementationVersion() on the built jar, it works, but the same does not work in a debugging environment where the jar is not built, but classes are available.
I am aware of using the Maven JAR plugin to generate the MANIFEST for a maven jar module. So one approach I am considering is to somehow create a copy of the MANIFEST in the generated sources output folder, which I include in my debug classpath. To achieve this:
Is it possible to generate the MANIFEST file in a custom location? If so, what is the plugin and execution configuration necessary?
If not, in which location is the file generated, so I may copy it my custom location using the maven-resources-plugin?
The Manifest file is created dynamically when the archive is assembled. There is no default way to do this.
The easiest I would come up with is to put a MANIFEST.MF in a resource directory, let Maven filter it and add the directory with a profile. This would mimic the way Maven Archiver creates your MANIFEST.MF. The hard way would be to create a custom plugin around Maven Archiver and pass the very same config as to the JAR plugin and enable it with a profile again.

include source files in war maven

I want to include source files also in Maven - War file . Some plugins in maven will do that but they are including source files in classes folder. But my requirement is that when I import the same war file again into eclipse I should be able to work on that war like any other normal war.
Basically I should be able to work on the same war after importing it to eclipse when I build maven project. (I'm using maven3. )
I remember that's not trivial because the war-plugin doesn't support the handy includes-configuration-element you know from the jar-plugin by default.
Therefore I suggest you to use the maven-assembly-plugin to configure the inclusion of your sourcefiles. You only need to define an assembly descriptor, where you list includes and excludes of your war-package. Maybe you can reuse one of the predefinied assembly descriptors to save some time.

IntelliJ: Including jars in a jar artifact

Developing on the Mac with IntelliJ 9.0.2 Community Edition.
I have a program which depends on two library jars. I have figured out how to get IntelliJ to make me a jar of my source (with the Artifact tab), and even to include the two jars in it.
However, if I get a listing of the jar file it produces, it looks like this:
com/acme/MyClass1.class
com/acme/MyClass2.class
...
mylib1.jar
myLib2.jar
And, no surprises, if I double-click the jar file, it gets a NoClassDefFoundError the first time it tries to access a class in one or other library jar.
It seems I need to tell IntelliJ to "inline" the library jars -- but this menu option is always greyed out!
Does anyone have any idea how to get jars inlined in a jar artifact?
IDEA doesn't support it yet, you can use Ant integration to package your jar (either by unpacking all the jars into the temp folder and then packaging the project output plus this temp folder into the single jar or by using some Ant task like jarjar).
If you want this feature to appear in the future IDEA versions, please vote for the request.
Having the dependency JARs included in your JAR should allow yoru code to run successfully. You probably don't have the JARs on your classpath.
I will use Maven Assembly plugin. Its simple and will give you a neat little jar file..
