Re: [m2e-users] (n00b Alert) why does my project build and execution environment change when converting to maven project?

Well what would you know, after a full day of restricted school internet, I come back home to a magically working Maven which builds on 1.6 :D . Thanks for your help guys :)

Tried it and even added the java 1.6 library but as soon as I hit update project it fell back to 1.5

What version of m2e are you using? Since m2e 1.1, if you start with no pom.xml and right-click on your eclipse project and Configure...>Convert to Maven..., the generated pom.xml is supposed to contain the maven-compiler-plugin configuration matching your Eclipse JDT settings.
If you already have a pom.xml, then, no settings conversion is done, m2e uses the already existing pom and you must do as Greg said.

This is really a Maven question, not a Maven on Eclipse (M2E) question, and probably better asked on users@xxxxxxxxxxxxxxxx

However, the reason is simply that Maven defaults to JDK 1.5. To change it, you'll want something like the following in your pom.xml ...


which configures the compiler plugin to use JDK 1.6

Sad to say that I am n00b to m2e (and to be fair, maven overall). I
really like the system, but one thing I don't get is when ever I
convert an existing project to a maven one or start a new maven
project the execution is always J2SE-1.5. Does anyone know why this is

Ps. The execution used to be JSE 6
