Cannot convert Maven AESv7 project to v8 #2919

Open briandealwis opened 6 years ago

briandealwis commented 6 years ago

With a native AES project, we can convert to a Java 8 project just by using <runtime>java8</runtime> in the appengine-web.xml. This doesn't work in Maven projects as the maven.compiler.source and maven.compiler.target determine the project Java facet version. But even after changing the maven.compiler.* properties, the project cannot be changed to Java 8 by adding the <runtime>java8</runtime> element.

But I can do it if I manually change the facets.
