Error doing "mvn package" on learnlib-release

[Teck Ping Khoo]

Hi everyone

I downloaded the release branch of learnlib and got the following error when I tried to do "mvn package". Seems to have a problem with "Observationtable"

Please let me know if I missed anything. Thanks.

Dear Teck Ping,


I assume you are using Windows? I believe this is an issue with the encoding of newlines (\n vs. \r\n) in one of the OT exporter tests. Normally, this should be handled by git, when cloning the repository. But when you simply download the branch/tag from the Github interface and extract the .zip (as a simple folder of arbitrary files), the .gitattributes are ignored.

Why do you want to build the release version yourself? All of the tagged versions are deployed to Maven Central [0] and can be directly included in your Maven project. You can also download the precompiled JARs from the central repository and use our special "distribution" artifact [1] (that bundles all transitive dependencies) for situations where you can't use Maven. If you need the current development versions, we even have nightly builds [2].

So unless you plan on building a custom version of LearnLib, this shouldn't be something you have to worry about.


Kind regards,
Markus
