Mavenenize project

[axkr]

Please create a Maven github action to automatically test and build a JAR for every commit:

• https://docs.github.com/en/actions/guides/building-and-testing-java-with-maven

Define Maven pom.xml

Define Maven folder structure:

• /src/main/java
• /src/main/ressources
• /src/test/java
• /src/main/ressources

Move JUnit dependencies to Maven test scope only

Yes, that would be recommendable. But priority is low for me.

A side note: For this kind of software, performance bugs are almost as much a bug as compiler errors. And they are harder to detect and need special testing. My performance tests are typically open end (on factor argument size) and terminated by the developer (me) when he has seen enough. This may take a long time, typically hours, sometimes days. So performance tests are not very well-suited to CI tests, I would say. Unless you convince me otherwise ;-)

Don't know your requirements exactly, but there are tools for these cases.

For example:

Thanks for pointing out. Don't see though how that approach could handle large test runtimes appropriately.

For testing smaller but performance sensitive parts of the code I recommend using the Java Microbenchmarking Harness - JMH:

• http://openjdk.java.net/projects/code-tools/jmh/
• https://github.com/openjdk/jmh

It is created by the developers of the openJDK them self, so I assume it is very sophisticated and reliable.

It is mainly distributed as Maven project and then quite straight forward to set it up. The following is one guide, but there are plenty others in the internet:

If you can relay on JMH it could speed up your performance tests significantly. You could even run them in the CI, but then it should be ensured that for each run the same hardware is used to get comparable results.

Finally I started the mavenization.

Unfortunately in Eclipse the individual file history seems to have gone lost although I was aware of the problem of the history when moving files in git.

Now I have loads of compiler errors if I restrict org.junit to the test scope because I used it for asserts in production code. This might take a few days.

[TilmanNeumann]

Now JUnit is restricted to the test scope.

Added Maven build for an executable jar. That should be all that was missing here...
