[MCOMPILER-372] Unable to compile modularized test code depending on test-jar

**[Jeronimo Backes](https://issues.apache.org/jira/secure/ViewProfile.jspa?name=jeronimobackes)** opened **[MCOMPILER-372](https://issues.apache.org/jira/browse/MCOMPILER-372?redirect=false)** and commented

I'm refactoring [univocity-parsers](https://github.com/uniVocity/univocity-parsers) into multiple projects with modules (attached a zip with everything I got)

However I'm unable to reliably build the attached project with its unit tests. Unpack then cd into "univocity-all-parent", then run "mvn clean install".

 

All projects generate test-jars, but for some reason class **com.univocity.parsers.core.routine.ResultSetWritingRoutine** inside "univocity-parsers-core/src/test/java/" is not found when compiling the tests of projects "univocity-csv", "univocity-tsv" and "univocity-fixedwidth".

 

Interestingly, the issue doesn't seem to be consistent as I got "univocity-csv" and "univocity-tsv" building without errors a few times. "univocity-fixedwidth" however failed consistently every single time.

Some of the errors I get are:

`[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.0:testCompile (default-testCompile) on project univocity-csv: Compilation failure: Compilation failure: `
`[ERROR] /home/jbax/dev/repository/univocity-all/univocity-oss/univocity-csv/src/test/java/com/univocity/csv/CsvWriterTest.java:[27,49] cannot find symbol`

I was also getting errors saying that the "Example" class was not found, or that the "printAndValidate" method was not found (that one comes from the univocity-output-tester dependency)..

 

There's something very weird going on and it's not consistently reproducible. If you for example change the code in the failing tests use "**import static com.univocity.parsers.core.routine.ResultSetWritingRoutine.*** " you may get a different set of errors. It's pretty intractable.

I hope this provides enough information, let me know if you need anything else.

Unpack univocity-all.zip, enter univocity-all-parent, and run mvn clean install to reproduce the failure. Start with the maven-compiler-plugin.MCOMPILER-372.patch and the test sources named in univocity-csv, univocity-tsv, and univocity-fixedwidth. Done means the modularized test code compiles reliably, including ResultSetWritingRoutine and the other reported test dependencies.
