Dear Geertjan, To answer both your posts:
I can't see any project option which corresponds to "source" or "target" with a value including "6". Which option are you referring to, please? It's a straight Java app using Swing. Generated originally on NB version <=8 (can't remember exactly which version - it was a long time ago) by the usual method - select "Java application" and click "New | JFrame" - design & program from there. HTH.

Yes, it is Ant-based. But what kind of project type -- a NetBeans Platform application? A Java EE application? An HTML/JavaScript application? What, exactly?

Use 7 or later. ??error: Target option 6 is no longer supported. Use 7 or later.??BUILD FAILED (total time: 0 seconds) I can't see any way of changing this as there aren't any project options to change the source or target, even if I knew what they were referring to. Stackoverflow gives remedies for this, but only for Maven. This project was built using Ant in NB 8 which I assume is carried over to NB 11. The only likely reference that I can see is in build-impl.xml which is firmly marked "DO NOT EDIT"! But the comment implies that the properties aren't being overridden correctly. <target depends="-pre-init,-init-private" name="-init-user"> ?? <property file="${user.properties.file}"/> ?? <!-- The two properties below are usually overridden --> ?? <!-- by the active platform. Just a fallback. --> ?? <property name="default.javac.source" value="1.6"/> ?? <property name="default.javac.target" value="1.6"/> ?? </target>?? Any ideas where to go from here please?
