Dear Geertjan and Laszlo, Thanks both for the help. But the source/binary field was already set to JDK12 (see the screenshot in my email of 12:01 yesterday).
It's very odd. I tried again yesterday after getting Geertjan's email and it built OK without my changing anything. Then I shut down the PC and booted it up this morning, and it's not building again with the same error messages. I don't think that anything has changed. I have a nasty feeling that I'm going to have to open a new project and copy all the files across.

I tried a new project using Maven and that does have tabs. So it seems to be an Ant problem.

When I change that to JDK 6, the two properties are changed for me to the following: javac.source=1.6 javac.target=1.6 Thanks, Gj On Mon, Jul 1, 2019 at 12:40 PM Geertjan Wielenga <geert...@apache.org> wrote: When I create a new Java SE project with Ant in NetBeans, I see these two in 'project.properties', you must have these too: javac.source=1.8 javac.target=1.8 Look in the Files window, in the 'nbproject' folder, to find 'project.properties' file.

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?

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?
