Re: [m2e-users] maven-dependency-plugin (goals

[Walt Boring <walter.boring@xxxxxx>]

I am having the a similar problem.   
I added the lifecycle mapping in my pom to force m2e to
 execute the maven-dependency-plugin, 
as I need to get my plugin to work properly.


<dependency>
<groupId>com.hp.oo.studio</groupId>
<artifactId>com.hp.oo.studio.debug.engine</artifactId>
<version>k2-SNAPSHOT</version>
</dependency>  	
  	
</dependencies>


<build>

<plugins>	
<plugin>
<!-- Use this plugin to copy all of the debug engine dependencies -->
<artifactId>maven-dependency-plugin</artifactId>
<executions>
<execution>
<id>copy jars</id>
<phase>test</phase>
<goals>
<goal>copy-dependencies</goal>
</goals>
<configuration>											
<outputDirectory>${project.build.directory}/classes/lib</outputDirectory>
<overWriteIfNewer>true</overWriteIfNewer>
<overWriteSnapshots>true</overWriteSnapshots>
/configuration>
</execution>
</executions>
</plugin>
</plugins>

<pluginManagement>
<plugins>
<plugin>
<groupId>org.eclipse.m2e</groupId>
<artifactId>lifecycle-mapping</artifactId>
<version>1.0.0</version>
<configuration>
<lifecycleMappingMetadata>
<pluginExecutions>
<pluginExecution>
<pluginExecutionFilter>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<versionRange>[2.0,)</versionRange>
<goals>
<goal>copy-dependencies</goal>
</goals>
</pluginExecutionFilter>
<action>
<execute />
</action>
</pluginExecution>
</pluginExecutions>
</lifecycleMappingMetadata>
</configuration>
</plugin>
</plugins>
</pluginManagement>


This fixes the standard "maven-dependency-plugin (goals "copy-dependencies", 
"unpack") is not
supported by m2e" error, but introduces another error.

I am now getting an error on the <execution> tag
"Error copying artifact from 
/home/waboring/devel/oo/infrastructure/k2_git/studio/studio-debug-engine/ta
rget/classes to 
/home/waboring/devel/oo/infrastructure/k2_git/studio/studio-debug-engine-pl
ugin/target/classes/lib/com.hp.oo.studio.debug.engine-k2-SNAPSHOT.jar 
(org.apache.maven.plugins:maven-dependency-plugin:2.3:copy-dependencies:copy 
jars:test)"


What is going on here?   This project depends on studio-debug-engine, which 
builds just fine.   
Then, m2 runs build on this project, which depends on studio-debug-engine 
project that 
produces a jar and gets stuffed into the local ~/.m2/repository area.  
Why is m2e trying to copy the jar from it's target/classes directory?   
The jar will never be in target/classes.  
the jar gets placed in <project>/target, not <project>/target/classes, or 
the local m2 cache.


Any help would be appreciated.
