在Maven项目之间共享测试资源 [英] Share test resources between maven projects

问题描述

有一个明确的解决方案，可以使用maven-jar-plugin插件的test-jar目标在maven项目之间共享通用测试代码(请参阅

There is a clear solution for sharing the common test code between maven projects using test-jar goal of maven-jar-plugin plugin (see here).

我需要对测试资源做类似的事情，特别是我希望在测试过程中项目A的测试资源在项目B的类路径中可用.

I need to do the similar thing with test resources, in particular, I want test resources of project A be available in the classpath of project B during testing.

对于项目A，需要声明:

For project A one need to declare:

<!-- Package and attach test resources to the list of artifacts: -->
<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-antrun-plugin</artifactId>
    <executions>
        <execution>
            <phase>package</phase>
            <goals>
                <goal>run</goal>
            </goals>
            <configuration>
                <tasks>
                    <jar destfile="${project.build.directory}/test-resources.jar">
                        <fileset dir="${project.basedir}/test-resources" />
                    </jar>
                </tasks>
            </configuration>
        </execution>
    </executions>
</plugin>
<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>build-helper-maven-plugin</artifactId>
    <executions>
        <execution>
            <phase>package</phase>
            <goals>
                <goal>attach-artifact</goal>
            </goals>
            <configuration>
                <artifacts>
                    <artifact>
                        <file>${project.build.directory}/test-resources.jar</file>
                        <type>jar</type>
                        <classifier>test-resources</classifier>
                    </artifact>
                </artifacts>
            </configuration>
        </execution>
    </executions>
</plugin>

在项目B中，它将是正常依赖项:

And in project B it will be normal dependency:

<dependency>
    <groupId>myproject.groupId</groupId>
    <artifactId>myartifact</artifactId>
    <version>1.0-SNAPSHOT</version>
    <classifier>test-resources</classifier>
    <scope>test</scope>
</dependency>

问题:它应该在所有情况下都有效吗?是否可以在没有maven-antrun-plugin的情况下打包资源(使用更多的轻量级"插件)?

Question: Should it work in all cases? Is it possible to pack resources without maven-antrun-plugin (using more 'lightweight' plugin)?

推荐答案

只需使用 jar:test-jar 并将声明的JAR声明为依赖项(请参阅

Just use jar:test-jar and declare the resulting JAR as a dependency (refer to this guide for more details). And while I don't understand the problem of having resources and classes in this jar, you can always exclude all .class files:

<project>
  <build>
    <plugins>
     <plugin>
       <groupId>org.apache.maven.plugins</groupId>
       <artifactId>maven-jar-plugin</artifactId>
       <version>2.2</version>
       <executions>
         <execution>
           <goals>
             <goal>test-jar</goal>
           </goals>
         </execution>
       </executions>
       <configuration> 
         <excludes>
           <exclude>**/*.class</exclude>
         </excludes>
       </configuration> 
     </plugin>
    </plugins>
  </build>
</project>

并使用它:

<project>
  ...
  <dependencies>
    <dependency>
      <groupId>com.myco.app</groupId>
      <artifactId>foo</artifactId>
      <version>1.0-SNAPSHOT</version>
      <type>test-jar</type>
      <scope>test</scope>
    </dependency>
  </dependencies>
  ...
</project>
