[jira] Created: (MEVENIDE-619) System dependencies lost when using assemblies

System dependencies lost when using assemblies
----------------------------------------------

                 Key: MEVENIDE-619
                 URL: http://jira.codehaus.org/browse/MEVENIDE-619
             Project: mevenide
          Issue Type: Bug
          Components: mevenide-netbeans
    Affects Versions: NB_3.1
         Environment: Java 6, NB 6.1 Dev
            Reporter: Daniel Mutch
            Assignee: Milos Kleint


Steps to reproduce:

1) Create a new maven project using standard archetype.

2) Add the following system dependency on javac

<dependency>
            <groupId>com.sun</groupId>
            <artifactId>tools</artifactId>
            <version>1.6.0</version>
            <scope>system</scope>
            <type>jar</type>
            <systemPath>${JAVA_6_HOME}/lib/tools.jar</systemPath>
</dependency>

This assumes you have a system variable declared for JAVA_6_HOME

3) In the main method of your class put the line

Main.compile(null);

and fix imports.

4) Compile

5) Firstly, right click (on file) and run. NPE will be observed as expected since we are passing null to the compile method.

6) Now right click on project, choose properties and set the main class.

7) Now run the project (instead of using run file). Instead of the NPE get message:

Exception in thread "main" java.lang.NoClassDefFoundError: com/sun/tools/javac/Main

Milos Kleint resolved MEVENIDE-619.
-----------------------------------

       Resolution: Fixed
    Fix Version/s: NB_3.1

I have rewritten the way run/debug projct is implemented fro j2se projects.
instead of a custom profile with a bunch of stuff in it, we will use just plain "mvn exec:exec java -classpath %classpath org.myapp.Main"

build #370 and later
http://deadlock.netbeans.org/hudson/job/mevenide/

I believe that gets rid of this issue as well. I haven't tried, please reopen if it doesn't help

Daniel Mutch reopened MEVENIDE-619:
-----------------------------------


It seems the new run / debug system has made the problem worse. Now it fails with class not found no matter how I try to run the application.

Milos Kleint updated MEVENIDE-619:
----------------------------------

    Component/s:     (was: mevenide-netbeans)
                 mevenide2-netbeans

ok, so it probably only worked because the exec:java goal runs in the same VM as the maven build, thus in the same VM as the IDE which has it on classpath I guess..
I'll have to try to debug the setup.

Milos Kleint commented on MEVENIDE-619:
---------------------------------------

http://maven.apache.org/guides/introduction/introduction-to-dependency-mechanism.html

system dependencies are similar to "provided" dependencies. as such these are not put in runtime classpath of the project. That's why the old setup failed and the new one is failing as well.

---------------------------------------

Ah...I see of course and applications are being run using the jre, so tools.jar is not available.

Daniel Mutch commented on MEVENIDE-619:
---------------------------------------

Sorry to give you the run around on this Milos, but I'm confused. It seems all of the Maven examples declare tools.jar as a system dependency but tools.jar isn't in the classpath for jre or jdk. So i fail to see what the standard way to get tools.jar into the runtime classpath is? Any suggestions? thanks

Milos Kleint commented on MEVENIDE-619:
---------------------------------------

indeed the system scope in general looks like a workaround only. it works only because the examples assume the compilation only.

the only solution that comes to mind is editing the action mapping and do exec:exec java -classpath <path-to-tools>:%classpath <main class>
