JavaParser reading a src directory

I've been using a CompilationUnit to parse Java files but now I'd like to parse all files within a directory.

I've tried the following however the compilation size is calculated as 0 when I expect it to be the number of Java files within the specified directory.

Path pathToSource = Paths.get("resources/src");
SourceRoot sourceRoot = new SourceRoot(pathToSource);
List<CompilationUnit> compilations = sourceRoot.getCompilationUnits();

Following the JavaDoc - https://www.javadoc.io/doc/com.github.javaparser/javaparser-core

Solution

  • You either have to add all the compilation units manually, or just call tryToParse() on the sourceRoot.

    With this small modification, it found (almost*) all .java files below the SourceRoot.

    Path pathToSource = Paths.get("resources/src");
SourceRoot sourceRoot = new SourceRoot(pathToSource);
sourceRoot.tryToParse();
List<CompilationUnit> compilations = sourceRoot.getCompilationUnits();

    (* it did not support java modules, so it failed to parse my module-info.java).
