Groovy file does not compile in Intellij IDEA

Question

I have maven project wit java and groovy tests. In command line maven compilation all tests are running, but in my IDEA project (which is created automatically, by "AutoImport maven projects", IDEA copies groovy files to /target/test-classes without compiling them.

My gmaven plugin looks like

    <plugin>
                <groupId>org.codehaus.gmaven</groupId>
                <artifactId>gmaven-plugin</artifactId>
                <version>1.3</version>
                <executions>
                    <execution>
                        <goals>
                            <goal>generateStubs</goal>
                            <goal>compile</goal>
                            <goal>generateTestStubs</goal>
                            <goal>testCompile</goal>
                        </goals>
                        <configuration>
                            <providerSelection>1.7</providerSelection>
                        </configuration>
                    </execution>
                </executions>
                <dependencies>
                    <dependency>
                        <groupId>org.codehaus.groovy</groupId>
                        <artifactId>groovy-all</artifactId>
                        <version>${groovy.version}</version>
                    </dependency>
                </dependencies>
            </plugin>

Solution 1

Solved by removing and creating from scratch IDEA project (ipr file)

Solution 2

I had the same issue and had to change in Idea the following setting: Settings->Compiler->Resource patterns

It was !?*.java

I changed it into !?.java;!?.form;!?.class;!?.groovy;!?.scala;!?.flex;!?.kt;!?.clj

It would be better to be able to specify it into the pom file though but haven't found a way yet.

Solution 3

GMaven plugin is only intended for maven compilation. Idea uses the Groovy compiler included in groovy-all jar. For Idea to get a hold of that add a project dependency, e.g.:

...
  <groupId>yourproject</groupId>
  <artifactId>yourproject</artifactId>
  <version>1.0.0-SNAPSHOT</version>

  <dependencies>
    <dependency>
      <groupId>org.codehaus.groovy</groupId>
      <artifactId>groovy-all</artifactId>
      <version>${groovy.version}</version>
    </dependency>
  </dependencies>
...

Solution 4

Please change folder type of groovy files as Source Root. Step for same is Right Click on folder -> Select option - 'Make Directory as' -> Source Root

Yes, I have such dependency. I even see it in IDEA module dependencies

[Nikita Volkov]

Try to go to ''Project Structure/Facets'' and set up the appropriate compiler for your module there. It should be in a drop down list of jars.

[Pavel Bernshtam]

I do not see "Groovy" in the list of Facets. What may be a reason?

[Nikita Volkov]

Ignore my comment about "Project Structure/Facets", it's not applicable to Groovy, sorry. 1. Check out whether your groovy sources are stored at /src/main/groovy or /src/test/groovy 2. Check out your run/debug configurations. The ''Make'' option must be checked 3. Try deleting Idea files and reimporting your POM 4. Try upgrading Idea to latest EAP

1. Yes, I have tests in src/test/groovy 2. Yes, I make or compile separate class individually I even created groovy as global library and added it to the module instead of Maven dependency - it does not help :(

[Pavel Bernshtam]

I have a module, where groovy compiles ok, but If I add this module to the existing project, it does not work

[jblack]

Changing my dependency from groovy to groovy-all fixed it for me.

what is the location of this file? (10 years and still feels relevant)
