不能依赖于maven程序集插件

Question

我有一个maven程序集插件的问题，我不明白为什么。

我想创建一个可执行的jar文件，但在生成的jar文件中缺少一些东西。

实际上，生成的jar不包含实际上在pom（common-loggins）中引用的依赖项，而所有其他依赖项都存在于生成的jar中。

在jar的执行过程中，我在commons-logging类上得到了一个“NoClassDefError”。

我已经包含了一个简化的pom，因此您可以测试以查看问题。

父POM具有一个托管DEPENDENCY于commons-洛

我不知道这么好这个插件，但你可能要考虑的可能性。

而不是汇编插件，使用阴影插件。 http://maven.apache.org/plugins/maven-shade-plugin/

  <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> 
         <configuration> 
          <createDependencyReducedPom>false</createDependencyReducedPom> 
          <filters> 
           <filter> 
            <artifact>*:*</artifact> 
            <excludes> 
             <exclude>META-INF/*.SF</exclude> 
             <exclude>META-INF/*.DSA</exclude> 
             <exclude>META-INF/*.RSA</exclude> 
             <exclude>.settings/**</exclude> 
             <exclude>*.classpath</exclude> 
             <exclude>*.project</exclude> 
             <exclude>*.txt</exclude> 
            </excludes> 
           </filter> 
          </filters> 
         </configuration> 
        </execution> 
       </executions> 
      </plugin> 

并创建一个完整的.exe包括全部或.exe其推出的所有一个.jar，使用launch4j插件https://github.com/lukaszlenart/launch4j-maven-plugin

  <plugin> 
       <groupId>com.akathist.maven.plugins.launch4j</groupId> 
       <artifactId>launch4j-maven-plugin</artifactId> 
       <version>1.5.2</version> 
       <executions> 
        <execution> 
         <id>l4j-gui</id> 
         <phase>package</phase> 
         <goals> 
          <goal>launch4j</goal> 
         </goals> 
         <configuration> 
          <headerType>gui</headerType> 
          <outfile>target/Project.exe</outfile> 
          <jar>target/${project.artifactId}-${project.version}.jar</jar> 
          <!-- if <dontWrapJar>true</dontWrapJar> change to this conf <jar>${project.artifactId}-${project.version}.jar</jar> --> 
          <dontWrapJar>false</dontWrapJar> 
          <errTitle>Error in launch4j plugin</errTitle> 
          <classPath> 
           <mainClass>path.Main</mainClass> 
          </classPath>
