IntelliJ + groovy DSL: How to exclude files from being compiled by groovy plugin?
groovy, groovydsl, intellij-idea, java, liquibase
Solution
Try removing the groovy file suffix from the compiler's resources list:
Settings -> Compiler
Problem
I am working on a Java web project that uses Liquibase groovy DSL to managae DB changes. For the sake of this topic, it could be any other 3rd party library that uses `*.groovy` files as sources. The project is built with gradle. In one of my modules (`dao-base`) under the `src/main/resources` folder I have groovy files (`changelog01.groovy, master_changelog.groovy` etc.). these files should be loaded by the liquibase jar at runtime. Now when I try to make the project in IntelliJ it gives the following error message: Groovyc: Cannot compile Groovy files: no Groovy library is defined for module 'dao-base'. I understood that the groovy plugin detects `*.groovy` files, tries to compile them and unsurprisingly fails. these are groovy DSL files that should be loaded only by the 3rd party liquibase parser and I don't need IntelliJ's groovy plugin to try and compile them. I managed to come up with 2 partial solutions: 1. disabling groovy plugin in intellij. The problem with this solution is that the gradle plugin depends on the groovy plugin and thus is automatically disabled when disabling the groovy plugin. I need the gradle plugin enabled. 2. excluding the `src/main/resources` folder in project settings --> modules --> `dao-base` (my module) --> sources tab. The problem with this solution is that when I build the project and deploy to tomcat, the files from the resources folder are missing and since the files in it are required in runtime, I get file not found exception when the war loads. I was hoping someone could come up with a better solution for this problem.
