我有一个如下所示的多模块maven设置,
+- pom.xml
+- module1/
+- pom.xml
+- module2/
+- pom.xml
module2
生成一个可执行jar及其依赖项复制到lib/
目录。 pom.xml
包含此内容,
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<executions>
<execution>
<id>copy-dependencies</id>
<phase>prepare-package</phase>
<goals>
<goal>copy-dependencies</goal>
</goals>
<configuration>
<outputDirectory>${project.build.directory}/module2/lib</outputDirectory>
<overWriteReleases>false</overWriteReleases>
<overWriteSnapshots>false</overWriteSnapshots>
<overWriteIfNewer>true</overWriteIfNewer>
<includeScope>runtime</includeScope>
</configuration>
</execution>
</executions>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<configuration>
<archive>
<manifest>
<addClasspath>true</addClasspath>
<classpathPrefix>lib/</classpathPrefix>
<mainClass>com.test.JksUtility</mainClass>
</manifest>
<manifestEntries>
<Class-Path>.</Class-Path>
</manifestEntries>
</archive>
<outputDirectory>${project.build.directory}/module2</outputDirectory>
</configuration>
</plugin>
当module1
引用module2
作为依赖项时,问题就变得明显了。在module1
&#39; s pom.xml
包含,
<dependency>
<groupId>com.test</groupId>
<artifactId>jksutil</artifactId>
<version>${jksutil.version}</version>
</dependency>
当我尝试运行module1
时,它告诉我它找不到module2
的任何依赖项,因为它需要lib/
存储库中.m2
目录下的所有jar。这是由于上面定义的classpathPrefix
。
例如,对于缺少的依赖项,我会收到以下错误,
java.io.FileNotFoundException: /Users/test/.m2/repository/com/test/jksutil/1.2.1-SNAPSHOT/lib/argparse4j-0.7.0.jar (No such file or directory)

除了创造一个胖子/超级罐子之外还有吗?

请尝试使用Maven Shade Plugin
构建可执行jar https://maven.apache.org/plugins/maven-shade-plugin/index.html
