Comments are not fully ignored in pom.xml.

The following lines in pom.xml

<!--executionEnvironment>J2SE-1.5</executionEnvironment>
<source-java-version>1.5</source-java-version>
<target-java-version>${source-java-version}</target-java-version-->

caused a build to fail with 1.5 no longer supported. Changing to 1.8 within the comments and everything is ok.

Please share a complete (at best executable) example, this snippet shows nothing that is directly relatable to Tycho and behavior obviously depends on the used version of Tycho and other plugins.

It's a simple parser bug. The <!-- ... --> gets confused by the internal < ... > allowing at least the <source-java-version>1.5</source-java-version> to be processed.

The please report this to the maven project, Tycho is not parsing the pom.xml
