Question

我有一个有很多依赖项的maven项目。我想使用程序集插件将所有依赖jar包装在一个带有依赖关系的jar中，但我并不是所有的依赖关系都不会在一个大混乱中解压缩。我希望他们所有人都进入lib文件夹，但我不知道如何添加类路径。我的pom：

Answer 1

他可能正在重新配置他的maven依赖插件：

Theta(f(n)) = Theta(n^0.51)

现在，当您的运行<plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-dependency-plugin</artifactId> <version>2.10</version> <executions> <execution> <id>copy</id> <phase>package</phase> <goals> <goal>copy-dependencies</goal> </goals> <configuration> <outputDirectory>${distDirectory}/lib</outputDirectory> <includeScope>runtime</includeScope> </configuration> </execution> </executions> </plugin>时，所有依赖关系罐都会转到mvn package（或者您的distDirectory）。

Answer 2

如果maven-jar-plugin没有在清单文件中生成条目Class-Path，尽管您已设置<addClasspath>true</addClasspath>，请确保您使用的是2.2或更新版本的插件。

2.1版中的错误MJAR-83似乎阻止插件在类路径中列出依赖项。

maven程序集创建具有依赖项和类路径的jar
