I'm developing for JavaFX8, so I'm using Java8-ea SDK (currently b120).
Recently I started using lambda (rationale was: since I'm using JavaFX8 anyways I can take vantage in the good things of Java8 also).
I had to change, in my parent pom:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.1</version>
<configuration>
<source>8</source>
<target>8</target>
</configuration>
</plugin>
This works as expected.
Problem is: when I ran "Maven -> Update Project..." eclipse "Preferences -> Java Compiler JDK Compliance" was reset to 1.4 on "project specific settings", while, obviously, "Workspace settings -> Java -> Compiler -> Compiler compliance level" remained at "1.8 (BETA)".
What did I do wrong?
