在maven项目之间共享测试资源

有一个明确的解决方案,可以使用test-jar插件的maven-jar-plugin目标在maven项目之间共享公共测试代码(请参阅here)。

我需要对测试资源做类似的事情,特别是,我希望项目A的测试资源在测试期间在项目B的类路径中可用。

对于项目A,需要声明:

<!-- 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,这将是正常的依赖:

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

问题:它应该适用于所有情况吗?是否可以在没有maven-antrun-plugin的情况下打包资源(使用更多'轻量级'插件)?

只需使用jar:test-jar并将生成的JAR声明为依赖项(有关详细信息,请参阅this guide)。虽然我不理解在此jar中拥有资源类的问题,但您始终可以排除所有.class个文件:

<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>

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>

公认的答案对我有所帮助,但是如果您还需要同一个项目的常规jar,它就不太准确。它将从两个jar中删除* .class文件。
以下设置转化为类似的内容:

  • 为我制造2个广口瓶,1个常规,1个测试;
  • 删除* .class文件,但只能从测试罐中删除

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

已经有一个目标是从maven构建test jar

假设您需要更灵活的东西,可以使用jar插件打包测试资源,并使用类似这样的主程序包目标来运行该目标。

      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-jar-plugin</artifactId>
        <executions>
          <execution>
            <phase>package</phase>
            <goals>
              <goal>jar</goal>
            </goals>
            <configuration>
              <classifier>test-resources</classifier>
              <includes>
                <include>**/*.whatever-you-want</include>
              </includes>
            </configuration>
          </execution>
        </executions>
      </plugin>

当运行jar目标时,捆绑的任何内容都将添加到project-name-version-test-resources.jar中。

然后,您可以通过上面使用的相同依赖项将其包含在项目中。

使用maven-dependency-plugin可以将所需的资源放在正确的目录中,只需修改依赖项目上的pom:

<plugin>
   <groupId>org.apache.maven.plugins</groupId>
   <artifactId>maven-dependency-plugin</artifactId>
   <executions>
      <execution>
         <phase>generate-test-resources</phase>
         <goals>
            <goal>unpack</goal>
         </goals>
         <configuration>
            <artifactItems>
               <artifactItem>
                  <groupId>dependeeGroupId</groupId>
                  <artifactId>dependeeArtifactId</artifactId>
                  <version>dependeeVersion</version>
                  <type>test-jar</type>
                  <outputDirectory>${project.build.directory}/test-classes</outputDirectory>
                  <includes>resourceNeeded.txt</includes>
                  <overWrite>true</overWrite>
               </artifactItem>
            </artifactItems>
         </configuration>
      </execution>
   </executions>
</plugin>

type用于获取测试资源
outputDirectory用于使资源在测试中可用
