I've configured my maven-compiler to use the Eclipse jdt compiler:

<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<version>2.3.2</version>
<inherited>true</inherited>
<dependencies>
<dependency>
<groupId>org.sonatype.tycho</groupId>
<artifactId>tycho-compiler-jdt</artifactId>
<!-- 0.11.x is equivalent to Eclipse 3.6.x/Helios; 0.12.x is 3.7/Indigo -->
<version>0.10.0</version>
</dependency>
</dependencies>
<configuration>
<source>1.6</source>
<target>1.6</target>
<showDeprecation>true</showDeprecation>
<showWarnings>true</showWarnings>
<compilerId>jdt</compilerId>
</configuration>
</plugin>

This works fine when using the configuration as above, but when I change the tycho-compiler-jdt to 0.11.1 the Jenkins build fails with:

[INFO] [resources:resources
