SebbASF commented on MCOMPILER-205:
-----------------------------------
[For completeness]
A work-round is to ensure that p-i files always generate output.
One way to do this is to add an annotation.
Unfortunately it appears that the only annotation which is guaranteed to be
available in Java 1.5+ is @Deprecated, which is obviously unsuitable. But it is
possible to create a dummy annotation, as follows:
{code:title=PackageMarker.java}
@Retention(RetentionPolicy.SOURCE)
public @interface PackageMarker { }
{code}
{code:title=package-info.java}
/**
* Example Package Javadoc
*/
@PackageMarker
package example;
{code}
This work-round is suitable for projects that have a mix of p-i files, some of
which already use annotations.
Excluding the p-i files from compilation is only suitable if the p-i files
contain Javadoc only.
