Question

我有两个模块，组件和应用程序。由于构建过程中稍后的依赖冲突（谷歌协议缓冲区），组件模块被着色。

<!-- snip from Component's pom.xml -->
<plugin>
     <groupId>org.apache.maven.plugins</groupId>
     <artifactId>maven-shade-plugin</artifactId>
     <version>2.3</version>
     <configuration>
         <relocations>
             <relocation>
                 <pattern>com.google.protobuf</pattern>                                
                 <shadedPattern>my.package.protocols.shaded.com.google.protobuf</shadedPattern>
             </relocation>
         </relocations>
     </configuration>
     <executions>
         <execution>
             <phase>package</phase>
             <goals>
                 <goal>shade</goal>
             </goals>
         </execution>
    </executions>
</plugin>

应用程序取决于组件模块。但是，Application中的源文件无法引用Component所依赖的着色库。这对于与Component进行交互至关重要。

     <-- snip from Application's pom.xml -->   
     <dependency>
          <groupId>my-group</groupId>
          <artifactId>component</artifactId>
          <version>${project.version}</version>
     </dependency>

即使IntelliJ找不到导入，Maven构建也能正常工作。我错过了什么/做错了什么？

Answer 1

太糟糕了，在使用JetBrains打开票证之后，此问题先前已报告过，目前在IntelliJ中不受支持。

Answer 2

我通过着色源jar并将其解压缩到源目录来解决类似的问题：

<build>

    <sourceDirectory>${project.build.directory}/shaded-sources</sourceDirectory>

    <plugins>
      <plugin>
        <artifactId>maven-source-plugin</artifactId>
        <configuration>
          <skipSource>true</skipSource>
        </configuration>
      </plugin>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-shade-plugin</artifactId>
        <version>3.1.0</version>
        <executions>
          <execution>
            <phase>package</phase>
            <goals>
              <goal>shade</goal>
            </goals>
            <configuration>
              <createSourcesJar>true</createSourcesJar>
              <shadeSourcesContent>true</shadeSourcesContent>
              <createDependencyReducedPom>false</createDependencyReducedPom>

                </includes>
              </artifactSet>
              <relocations>
                <relocation>
                  <pattern>com.google.common</pattern>
                  <shadedPattern>org.apache.drill.shaded.com.google.common</shadedPattern>
                </relocation>
              </relocations>
            </configuration>
          </execution>
        </executions>

              </artifactItems>
            </configuration>
          </execution>
        </executions>
      </plugin>
</build>

Answer 3

build-helper-maven-plugin似乎已将阴影罐添加到IntelliJ项目中：

  <plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>build-helper-maven-plugin</artifactId>
    <executions>
      <execution>
        <id>compile</id>
        <phase>package</phase>
        <goals>
          <goal>attach-artifact</goal>
        </goals>
        <configuration>
          <artifacts>
            <artifact>
              <file>${basedir}/target/<YOUR JAR NAME>-SNAPSHOT.jar</file>
              <type>jar</type>
              <classifier>optional</classifier>
            </artifact>
          </artifacts> 
        </configuration>
      </execution>
    </executions>
  </plugin>

Answer 4

我在当前项目中使用的另一种解决方案。

对于着色模块或自定义包，其工作方式相同。

Answer 5

更好的解决方法似乎是：在IntelliJ的项目视图中，右键单击碎片项目“组件”-> pom.xml，选择“ Maven”->“忽略项目”。然后在项目pom.xml上执行“ Maven”->“重新导入”。

让IntelliJ在多模块maven项目中导入着色依赖项
