Description Dénes Harmath

Build Identifier: I20110613-1736

After adding the Xtend libs to the classpath in Eclipse, .classpath looks like:

<?xml version="1.0" encoding="UTF-8"?>
<classpath>
	<classpathentry kind="src" path="src/main/xtend-gen"/>
	<classpathentry kind="src" output="target/classes" path="src/main/java"/>
	<classpathentry kind="src" output="target/test-classes" path="src/test/java"/>
	<classpathentry kind="con" path="org.eclipse.xtend.XTEND_CONTAINER"/>
	<classpathentry excluding="**" kind="src" output="target/classes" path="src/main/resources"/>
	<classpathentry excluding="**" kind="src" output="target/test-classes" path="src/test/resources"/>
	<classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/J2SE-1.5"/>
	<classpathentry kind="con" path="org.maven.ide.eclipse.MAVEN2_CLASSPATH_CONTAINER"/>
	<classpathentry kind="output" path="target/classes"/>
</classpath>

But I use Xtend in a Maven project, and don't want to commit .classpath into the VCS, so I run maven eclipse:clean eclipse:eclipse. It generates the following .classpath:

<classpath>
  <classpathentry kind="src" path="src/test/java" output="target/test-classes" including="**/*.java"/>
  <classpathentry kind="src" path="src/test/resources" output="target/test-classes" excluding="**/*.java"/>
  <classpathentry kind="src" path="src/main/java" including="**/*.java"/>
  <classpathentry kind="src" path="src/main/xtend-gen" including="**/*.java"/>
  <classpathentry kind="src" path="src/main/resources" excluding="**/*.java"/>
  <classpathentry kind="output" path="target/classes"/>
  <classpathentry kind="var" path="M2_REPO/com/google/guava/guava/10.0.1/guava-10.0.1.jar" sourcepath="M2_REPO/com/google/guava/guava/10.0.1/guava-10.0.1-sources.jar"/>
  <classpathentry kind="var" path="M2_REPO/com/google/code/findbugs/jsr305/1.3.9/jsr305-1.3.9.jar"/>
  <classpathentry kind="var" path="M2_REPO/org/eclipse/xtend2/org.eclipse.xtend2.lib/2.2.0/org.eclipse.xtend2.lib-2.2.0.jar" sourcepath="M2_REPO/org/eclipse/xtend2/org.eclipse.xtend2.lib/2.2.0/org.eclipse.xtend2.lib-2.2.0-sources.jar"/>
  <classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER"/>
</classpath>

After it, Xtend can't compile .xtend files. There are no errors, but the Java sources are not generated.

Reproducible: Always

Can you also attach your .project file before and after mvn clean?

Note that Eclipse automatically adds the missing Xtext builder entries when opening an .xtend file but this does not solve the incremental compilation.

pls configure your maven eclipse plugin to also include  *.xtend files
e.g.

     <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-eclipse-plugin</artifactId>
        <version>2.8</version>
        <configuration>
          <sourceIncludes>
            <sourceInclude>**/*.xtend</sourceInclude>
          </sourceIncludes>
        </configuration>
      </plugin>

see http://maven.apache.org/plugins/maven-eclipse-plugin/examples/specifying-source-path-inclusions-and-exclusions.html

please reopen if i missed something
