I am trying to use windup for an application that should be its main use case - porting an application from web logic to Jboss - and find that it looks tantalizingly close to usable, but every attempt to use it hits a brick wall somewhere or other. I've tried with the legacy 0.6.8 downloadable binary. I am using source mode. On some directories, useful output is produced. On others, I get a null pointer exception: Exception in thread "main" java.lang.NullPointerException at org.jboss.windup.interrogator.impl.JavaInterrogator.populateMeta(JavaInterrogator.java:153) at org.jboss.windup.interrogator.impl.JavaInterrogator.fileEntryToMeta(JavaInterrogator.java:97) at org.jboss.windup.interrogator.impl.JavaInterrogator.fileEntryToMeta(JavaInterrogator.java:43) at org.jboss.windup.interrogator.impl.ExtensionInterrogator.processFile(ExtensionInterrogator.java:76) at org.jboss.windup.interrogator.DirectoryInterrogationEngine.process(DirectoryInterrogationEngine.java:71) at org.jboss.windup.WindupMetaEngine.processSourceDirectory(WindupMetaEngine.java:190) at org.jboss.windup.WindupMetaEngine.getArchiveMeta(WindupMetaEngine.java:156) at org.jboss.windup.WindupReportEngine.generateReport(WindupReportEngine.java:121) at org.jboss.windup.WindupMain.processInput(WindupMain.java:144) at org.jboss.windup.WindupMain.main(WindupMain.java:71) From the source code I can find, I see that this problem may have been addressed (the line number in JavaInterrogator.java in the latest versions can't be the site of an exception throw) so I've tried some of the other builds that are available. I've tried some of the source zips on github. None of these build. There's always some unresolved dependency. I've tried a download from the latest source on Github. This DOES build, but how to execute it? Following the instructions here: https://github.com/windup/windup I find everything in order until I go to run windup: $ ./forge Using Forge at /home/scohen/forge-distribution-2.7.2.Final Warning: JAVA_HOME environment variable is not set. _____ | ___|__ _ __ __ _ ___ | |_ / _ \| `__/ _` |/ _ \ \\ | _| (_) | | | (_| | __/ // |_| \___/|_| \__, |\___| |___/ JBoss Forge, version [ 2.7.2.Final ] - JBoss, by Red Hat, Inc.

[bin]$ [bin]$ run-windup-1-x --input ~/vtone/build --output ~/vtone/windupreports --packages com.whatever --sourceMode true ***ERROR*** Could not run Windup How can I figure out what windup is objecting to? This error message is not in the least helpful. So my questions is now, for a non-developer of Windup, what version to use? Presumably the stable (or "legacy") version would be the choice but what do if exceptions are found there? Where is the source for the downloadable binary on the site? If using the unstable bleeding edge versions, where are USABLE directions for use that don't lead somewhere, unlike the above? Thanks for you help.
