Java application class files are not rebuilt if deleted

I can create a default “Hello World!” application through File > New > MicroEJ Standalone Application Project which builds and simulates as expected.

If I remove the bin folder (and others that were generated bnot in the default project) and perform a rebuild, the SOAR process fails as the Main.class file is not regenerated. Touching the file can force it to be rebuilt, but this is undesirable. Is there a step I am missing to regenerate application dependencies?
Yes :roll_eyes: Window > Preferences > Java > Compiler > Building > Output Folder > Rebuild class files modified by others… of course.

Also, is there a way to remove/correct the EasyAnt Console error seen below, when using a project source platform?
