It is just strange given Maven's popularity and years of use that underlying things are not more known. I may have to start hunting down some of those developers directly... The other option is to move away from the mdo files, Which would drop the dependency on Modello at least. That is my biggest issue, processing the mdo files into java files for compile. Plexus can remain, as its a runtime depdenency. Modello I believe is just a build one. Or move to something else, antlr, javacc, jaxb, xlc, etc Tons of things to generate Java files. Seems like nothing other than Maven uses Modello. And few are familiar with that. I have less issues with Plexus. Though I believe my issues with Modello come from it being built on top of Plexus. It uses Plexus for loading plugins, etc. > For me this case is too specific, it would take quite some time to > dive into, while many, many other issues are waiting as well to be > fixed. And in fact, your issue starts with this sentence "I am doing > abnormal things!" :) Abnormal, meaning I am building maven from source. Which most do not do. Those who do, likely use Maven to build Maven... Which I cannot do, thus the dilemma. People have tried and failed at integrating Maven with Gentoo's Portage. They are conflicting technologies same with Gradle. At least Ant + Ivy, the ivy parts could be bypassed and if any did any downloading stop that. That is not really an option with Maven or Gradle. Not to mention the whole bootstrapping issue to build using provided build systems. That said, Modello has a CLI. Using ModelloCLI to process mdo files should not really require voodoo or be considered anything that abnormal. It just seems like no one uses the mdo format outside of Maven. Anyone who does likely uses the Modello Maven Plugin. https://github.com/codehaus-plexus/modello/blob/master/modello-core/src/main/java/org/codehaus/modello/ModelloCli.java https://github.com/codehaus-plexus/modello/tree/master/modello-maven-plugin I was happy to see ModelloCLI, sad it does not work. I made a similar CLI for jaxb. Which I use to process files for Jersey. https://github.com/javaee/jaxb-istack-commons/pull/2 > Based on the analysis in the comments the issue does seem to be > having 2 instances instead of 1.

I have all sorts of Java code generators to generate Java code from some other format. Nothing has ever stumped me like this. I have put in all sorts of debugging code. Tons of various trial and error. None have shown any signs of progress even. > If you find the bug and are able to fix it, please provide a PR so we > can improve Modello. I cannot tell if its a bug, or a design change. It seems like the CLI does not fully load all plugins. Not sure if that is a code issue, something in the plexus component.xml files, not having a plexus.xml, or some other issue like the versions in use. -- William L. Thomson Jr.
