Description of problem:

Missing "org.eclipse.jdt.core.javanature" under "natures" tag in ".project" file results in no analysis of Java source code

When executing "windows-mta-cli analyze", ".project" file and ".setting" folder are created under source folder. But it does not seem that static-report contains the result of analysis for Java source codes.
It seems that the analysis result is contained if the element "org.eclipse.jdt.core.javanature" is added under "natures" tag in ".project" file [1].

If it is not expected for user to add the element "org.eclipse.jdt.core.javanature" to contain the analysis result for Java source codes, please fix.
