[m2e-users] Error: Path must include project and resource name
|
I have recently changed the setup of a project and received this error:
java.lang.IllegalArgumentException: Path must include project and
resource name: /og-analytics
at org.eclipse.core.runtime.Assert.isLegal(Assert.java:63)
at org.eclipse.core.internal.resources.Workspace.newResource(Workspace.java:2069)
at org.eclipse.core.internal.resources.Container.getFolder(Container.java:201)
at org.eclipse.m2e.jdt.internal.AbstractJavaProjectConfigurator.isContained(AbstractJavaProjectConfigurator.java:469)
at org.eclipse.m2e.jdt.internal.AbstractJavaProjectConfigurator.isNonOverlappingResourceDescriptor(AbstractJavaProjectConfigurator.java:461)
at org.eclipse.m2e.jdt.internal.AbstractJavaProjectConfigurator.addResourceDirs(AbstractJavaProjectConfigurator.java:422)
It causes an error popup every time the m2e project is updated, which
is of course very annoying.
I couldn't figure out what it was at first, and tried various things.
However, I finally figured out the following.
In our corporate-pom, we had added the following:
<resources>
<resource>
<directory>src/main/resources</directory>
</resource>
<resource>
<directory>${basedir}</directory>
<targetPath>META-INF</targetPath>
<includes>
<include>NOTICE.txt</include>
<include>LICENSE.txt</include>
</includes>
</resource>
</resources>
<!-- Include NOTICE/LICENSE in test jar files -->
<testResources>
<testResource>
<directory>src/test/resources</directory>
</testResource>
<testResource>
<directory>${basedir}</directory>
<targetPath>META-INF</targetPath>
<includes>
<include>NOTICE.txt</include>
<include>LICENSE.txt</include>
</includes>
</testResource>
</testResources>
It is these additional resource directories, based off ${basedir} that
cause the error. When the setup is changed back to the default the
error goes away:
<resources>
<resource>
<directory>src/main/resources</directory>
</resource>
</resources>
<testResources>
<testResource>
<directory>src/test/resources</directory>
</testResource>
</testResources>
In my view, this setup should not cause m2e any problems (and I
believe that in Eclipse Luna it was fine). I'll leave it up to you
guys as to whether you want to treat it as a bug to be fixed or not,
as I have my solution now!
thanks
