---------------------------------------
Resolution: Information Provided

> Key: MPLUGIN-476
> URL: https://issues.apache.org/jira/browse/MPLUGIN-476
> Project: Maven Plugin Tools
> Issue Type: New Feature
> Components: Plugin Plugin
> Affects Versions: 3.9.0
> Reporter: Ernst Reissner
> Priority: Major
>
> I write a plugin (https://github.com/Reissner/latex-maven-plugin)
> and `mvn clean deploy` results in following message:
> ```
> [INFO] --- plugin:3.9.0:descriptor (default-descriptor) @ latex-maven-plugin

> [INFO] Using 'UTF-8' encoding to read mojo source files.

> After long search (1 night) I found the following 'reason':
> ```
> package eu.simuline.m2latex.core;
> public enum Target {
> txt() {
> private final String TXT_OUTPUT_FILES = "^T$T\\.txt$";
> // may throw BuildFailureException TEX01
> public void processSource(LatexProcessor latexProcessor,
> LatexMainDesc desc) throws
> BuildFailureException {
> latexProcessor.processLatex2txt(desc);
> }
> public String getPatternOutputFiles(Settings settings) {
> return "^T$T\\.txt$";
> }
> }, ...;
> ...
> }
> ```
> Removing the line
> ```
> private final String TXT_OUTPUT_FILES = "^T$T\\.txt$";
> ```
> 'resolves' the problem.
> I feel this could indicate not just a bug but a conceptual flaw.
