Cannot add module in Intellij Idea

Question

I want to add lucene library to my project and modify it's core methods . I already have used lucene .jar files and that was the time when I didn't need modifying lucene core codes. But then I figure out that .jar files are pre-compiled files and we couldn't modify them at all.

Actually I googled almost every related page to find the solution (for many hours), but it seems that there is no helpful link on web!

This is the link I found apparently useful. So I get the lucene 6.3.0 from github and followed the steps suggested by the writer.

After all nothing helped me in this way and I got plenty of errors in IntellijIdea! This is the first error:

Error:Cannot compile Groovy files: no Groovy library is defined for module 'Balog2'

Any help would be appreciated, thanks.

Answer 1

What are you using for dependency management? Your submodule likely does not have groovy as a dependency and therefore cannot locate the groovy compiler

https://mvnrepository.com/artifact/org.codehaus.groovy/groovy-all

go here, pick a version of groovy that jives with the the java runtime you're using and add it to whatever dependency management solution you're using
