I have switched to Tycho 1.0.0 now. Andreas Sewe. I don't understand what you said after the sentence about being on tycho 1.0.0
What would be helpful is to have the section from the effective POM (mvn
help:effective-pom) that deals with the tycho-compiler-plugin, as there
are multiple settings (<useProjectSettings>, <useJDK>, <source>,
<target> [2]) that may be relevant here.
What exactly should i set?
This is what my effective_pom looks like for the tycho_colpiler_plugin section
<plugin>
<groupId>org.eclipse.tycho</groupId>
<artifactId>tycho-compiler-plugin</artifactId>
<version>1.0.0</version>
<executions>
<execution>
<id>default-compile</id>
<phase>compile</phase>
<goals>
<goal>compile</goal>
</goals>
<configuration>
<compilerArgs>
<arg>-warn:-raw,unchecked</arg>
</compilerArgs>
</configuration>
</execution>
</executions>
