With the following code

	@Inject
	@WithAttributes(shortName = 's', label = "source", required = true, type = InputType.JAVA_CLASS_PICKER)
	private UIInput<JavaResource> source;

Assume the following directory structure:
x/y/src/main/java/x.java

• Start forge in folder X.
• cd to some sub folder Y
• trigger the 'source' field
  • command --source src/main/java/x.java

The JavaResource fail to resolve the underlying file as it's pointing to:
X/src/main/java/x.java

It seems it's missing the updated 'current dir' and only resolve from 'original working dir'
