大家好!我一直试图使用Maven Shade Plugin来获取jar,但我仍然没有获得成功:(
这是我的项目结构:
MainModule
-Module1
-src
-pom.xml
-Module2
-src
-pom.xml
-pom.xml
Module1(pom.xml):
<parent>
<artifactId>MainModule</artifactId>
<groupId>com.plugintest</groupId>
<version>1.0-SNAPSHOT</version>
</parent>
<modelVersion>4.0.0</modelVersion>
<artifactId>Module1</artifactId>
Module2(pom.xml):
<parent>
<artifactId>MainModule</artifactId>
<groupId>com.plugintest</groupId>
<version>1.0-SNAPSHOT</version>
</parent>
<modelVersion>4.0.0</modelVersion>
<artifactId>Module1</artifactId>
MainModule(pom.xml):
<groupId>com.plugintest</groupId>
<artifactId>MainModule</artifactId>
<packaging>pom</packaging>
<version>1.0-SNAPSHOT</version>
<modules>
<module>Module1</module>
<module>Module2</module>
</modules>
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
<version>2.2</version>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>shade</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
根据这段代码,我得到2个jar文件(Module1-version.jar和Module2-version.jar)。但这不是我想要的。我希望获得1个jar文件(MainModule-version.jar),其中包含另一个(Module1和Module2)。
请告诉我,为什么这个Shade插件不起作用?
答案 0 :(得分:14)
你MainModule
不应该生成一个jar文件。它只能生成... pom文件。它包含所有子模块共享的配置。这就是针对每个模块调用shade插件的原因。
相反,创建第三个模块。我们称之为FinalModule
。此模块是MainModule
的孩子。将整个<build>
节点从MainModule
pom.xml移动到FinalModule
pom.xml。
文件结构:
MainModule -FinalModule -src -pom.xml -Module1 -src -pom.xml -Module2 -src -pom.xml -pom.xml
FinalModule
pom.xml
如下所示:
FinalModule(pom.xml)
<parent>
<groupId>com.plugintest</groupId>
<artifactId>MainModule</artifactId>
<version>1.0-SNAPSHOT</version>
</parent>
<artifactId>FinalModule</artifactId>
<dependencies>
<dependency>
<groupId>com.plugintest</groupId>
<artifactId>Module1</artifactId>
<version>1.0-SNAPSHOT</version>
</dependency>
<dependency>
<groupId>com.plugintest</groupId>
<artifactId>Module2</artifactId>
<version>1.0-SNAPSHOT</version>
</dependency>
</dependencies>
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
<version>2.2</version>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>shade</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
最后,你应该得到这样的东西:
