I have a Grails 2.3.7 project which should use Java 1.7. I am using the Spring GGTS IDE as development tool and it is configured to use a Java 1.7 JDK.
I created the project in GGTS and changed the source and target level to 1.7. Then I generate a maven pom file with the create-pom command. So far so good. The project is linked to use a JRE System Library of version 1.7.
Then I change the project to be a Maven project in GGTS. What happens now is that in GGTS, the project changes the JRE System Library to become of version 1.6. I can manually switch it back to a java 1.7 library but every time I do a "Maven update project", the 1.6 library is back.
What am I doing wrong?
By removing the jre 1.6 as installed jre from GGTS, the project will use my jre 1.7. But in the list of linked dependencies it is still labeled JRE System Library [Java-SE 1.6] even though it points to my 1.7 instance. This solved my build-issues even though it still looks wrong.
