I have tried this already, but unfortunately it does not work (although I am not
experienced with maven).
I changed the source and target tags in adf-faces/pom.xml as below:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<inherited>true</inherited>
<configuration>
<excludes>
<exclude>**/.ade_path/**</exclude>
</excludes>
<testExcludes>
<exclude>**/.ade_path/**</exclude>
</testExcludes>
<compilerVersion>1.5</compilerVersion>
<source>1.5</source>
<target>1.4</target>
</configuration>
</plugin>
but get the error:
[INFO] Compilation failure
Failure executing javac, but could not parse the error:
javac: source release 1.5 requires target release 1.5
