Set default java compliance level for Maven projects in Eclipse

Question

The default compliance level for Maven is 1.5 and every time that I update a maven project in Eclipse it sets back the compliance level from 1.6 to 1.5 which is really annoy

Answer 1

I know that I can set the target to 1.6 in pom file but the problem is that I cannot set this in the parent pom and expect the children to inherit it.

Setting the and version in the parent pom does work.

For example, in my parent pom, I have:

  
    
      org.apache.maven.plugins
      maven-compiler-plugin
      2.3.2
      
        1.6
        1.6
        UTF-8
      
    
  

If you are having problems, you might want to check that:

• the child specifies the correct version of the parent;
• the parent pom specifies both source and target values;
• you have run mvn install on the parent; and
• mvn help:effective-pom on the child project shows the expected source/target values.

After modifying the poms, you may need to select both projects and use Maven->Update Project.
