IntelliJ + Groovy + Spock

问题:

I have been trying to create a Groovy project with Spock testing in IntelliJ IDEA.

Here are steps that I followed:

1. Created Groovy project and added Maven support.
2. Added Spock dependencies and plugin. I am using POM very similar to this one: https://github.com/mariuszs/java-spock-test-sample/blob/master/pom.xml
3. Due to conflicting Groovy dependency I removed Groovy 2.2 library from the Module Settings->Libraries. This allowed me to run tests.
4. I created a Groovy class in "src/main".. but I get the error when I try to run it:

Groovyc: Cannot compile Groovy files: no Groovy library is defined for module...

I am probably missing something because I am tired of trying different configurations for half of the day.

For fully groovy project try GMavenPlus

Sample project: https://github.com/mariuszs/groovy-maven-sample

Install GMavenPlus IntelliJ Plugin. IntelliJ dont recognize source directories src/main/groovy, configure this manually as shown below from Project Settings -> Modules window:.

Configuration

<project>
  <build>
    <plugins>
      <plugin>
        <groupId>org.codehaus.gmavenplus</groupId>
        <artifactId>gmavenplus-plugin</artifactId>
        <version>1.5</version>
        <executions>
          <execution>
            <goals>
              <goal>compile</goal>
              <goal>testCompile</goal>
            </goals>
          </execution>
        </executions>
      </plugin>
    </plugins>
  </build>
  <dependencies>
    <dependency>
      <groupId>org.codehaus.groovy</groupId>
      <artifactId>groovy-all</artifactId>
      <version>2.4.4</version>
    </dependency>
    <dependency>
        <groupId>org.spockframework</groupId>
        <artifactId>spock-core</artifactId>
        <version>1.0-groovy-2.4</version>
        <scope>test</scope>
    </dependency>     
  </dependencies>
</project>

There were two steps to fixing the (broken) project:

1. Update the groovy-all dependency to version 2.2.1, which I had installed on my machine.
2. In "projectName.iml" file replace

orderEntry type="library" exported="" scope="TEST" name="Maven: org.codehaus.groovy:groovy-all:2.2.1" level="project"

with this one:

<orderEntry type="library" name="groovy-2.2.1" level="application" />

This situation was caused by two factors: me being new to the IDE and the fact that things kinda-sorta work even when you mis-configure the project. I still think this Q&A might be useful to someone in the future.

回答3:

I had this "Cannot compile Groovy files: no Groovy library is defined for module" issue recently. I needed to mark my groovy test directory as a 'Test Sources Root' in IntelliJ.

Right click on dir --> Mark Directory as --> Test Sources Root

For me the solution was to open a .groovy file in the specific folder/module and then idea gave a little popup showing the the Groovy SDK is not configured. Then I clicked on configure -> OK and voila.
