我的目标是从pom中的依赖列表创建一个具有特定依赖关系的jar。我是这样使用maven-dependency-plugin:
String sql = "DELETE FROM course
WHERE (username_entry = " + username +
" AND course_name = " + courseToDelete.toUpperCase() + ")";
和一个assembly.xml文件:
<plugin>
<artifactId>maven-dependency-plugin</artifactId>
<executions>
<execution>
<id>copy-dependencies</id>
<goals>
<goal>unpack-dependencies</goal>
</goals>
<phase>prepare-package</phase>
<configuration>
<includeScope>runtime</includeScope>
<excludes>META-INF/*.SF,META-INF/*.DSA,META-INF/*.RSA</excludes>
<outputDirectory>${project.build.directory}/uber-deps/</outputDirectory>
</configuration>
</execution>
</executions>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-assembly-plugin</artifactId>
<executions>
<execution>
<phase>package</phase>
<configuration>
<transformers>
<transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
<mainClass>com.some.blaClass</mainClass>
</transformer>
</transformers>
</configuration>
</execution>
</executions>
</plugin>
<assembly xmlns="http://maven.apache.org/ASSEMBLY/2.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/ASSEMBLY/2.0.0 http://maven.apache.org/xsd/assembly-2.0.0.xsd">
<id>plugin</id>
<formats>
<format>jar</format>
</formats>
<includeBaseDirectory>false</includeBaseDirectory>
<dependencySets>
<dependencySet>
<outputDirectory>/</outputDirectory>
<useProjectArtifact>true</useProjectArtifact>
<unpack>true</unpack>
<scope>runtime</scope>
<includes>
<include>
${project.build.directory}/uber-deps/
</include>
</includes>
<excludes>
<exclude>*:sources</exclude>
</excludes>
</dependencySet>
</dependencySets>
</assembly>
之后所有相关的依赖关系都出现在target / uber-deps中,正如我所期望的那样。 我的问题是使用mvn clean install
下的下一个插件 - maven-assembly-plugin。在我看来,好像它没有采取超级计划。
我只是通过尝试使用<plugins>
解压缩jar来了解这一点,以查看uber-deps中的deps是否包装在jar xf
之后创建的jar中。
应该改变什么?
答案 0 :(得分:1)
1)
您将作为./target/<artifactId>-plugin.jar
的一部分构建的jar将被调用(默认情况下)plugin
请注意,id
部分是您在程序集xml文件中fileSets
下的内容。
2)
由于您已将依赖项解压缩到文件夹,因此应使用dependencySets
而不是<fileSets>
<fileSets>
<fileSet>
<outputDirectory>/</outputDirectory>
<includes>
<include>
${project.build.directory}/uber-deps/
</include>
</includes>
</fileSet>
</fileSets>
</fileSets>
:
fileSet
3)
顺便说一句,如果你想在你的jar中你自己的项目的输出,你应该添加另一个<fileSet>
<outputDirectory>/</outputDirectory>
<includes>
<include>
${project.build.outputDirectory}
</include>
</includes>
</fileSet>
:
shade-plugin
4)还要注意,您的程序集插件定义没有说明程序集xml文件的位置,并且您尝试使用src/assembly/plugin.xml
配置定义mainClass。这是它在程序集插件中的外观(假设您的程序集文件位于<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-assembly-plugin</artifactId>
<executions>
<execution>
<phase>package</phase>
<configuration>
<descriptors>
<descriptor>src/assembly/plugin.xml</descriptor>
</descriptors>
<archive>
<manifest>
<mainClass>com.some.blaClass</mainClass>
</manifest>
</archive>
</configuration>
</execution>
</executions>
</plugin>
