scala和maven的可执行jar

我想用scala和maven创建可执行jar。我使用maven-scala-plugin和maven-assembly-plugin，但在我看来，程序集插件被忽略。我得到的jar没有依赖关系，并包含没有主类行的清单。scala和maven的可执行jar

<plugins> 
     <plugin> 
      <groupId>org.scala-tools</groupId> 
      <artifactId>maven-scala-plugin</artifactId> 
      <version>2.15.0</version> 
      <executions> 
       <execution> 
        <goals> 
         <goal>compile</goal> 
        </goals> 
       </execution> 
      </executions> 
     </plugin> 

     <plugin> 
      <artifactId>maven-assembly-plugin</artifactId> 
      <configuration> 
       <archive> 
        <manifest> 
         <mainClass>org.example.MainClass</mainClass> 
        </manifest> 
       </archive> 
       <descriptorRefs> 
        <descriptorRef>jar-with-dependencies</descriptorRef> 
       </descriptorRefs> 
      </configuration> 
     </plugin> 
    </plugins>

您使用什么命令来构建？你可能想检查接受答案的下半部分[这个非常流行的问题]（http://stackoverflow.com/questions/574594/how-can-i-create-an-executable-jar-with-dependencies-使用maven）并且可能添加一个'executions'部分。还请注意这些意见，其中提出了其他有用的问题。 – 2014-09-19 15:03:41

maven-scala-plugin已弃用，由2+年代以来由scala-maven-plugin取代。 scala-plugin不会修改依赖关系等。我认为你的问题来自maven-assembly-plugin的使用。 – 2014-09-20 12:12:12

  <plugin> 
      <groupId>org.apache.maven.plugins</groupId> 
      <artifactId>maven-jar-plugin</artifactId> 
      <version>3.0.2</version> 
      <configuration> 
       <archive> 
        <manifest> 
         <addClasspath>true</addClasspath> 
         <mainClass>com.example.MyClass</mainClass> 
         <classpathLayoutType>custom</classpathLayoutType> 
         <customClasspathLayout>lib/$${artifact.artifactId}-$${artifact.version}$${dashClassifier?}.$${artifact.extension}</customClasspathLayout> 
        </manifest> 
       </archive> 
      </configuration> 
     </plugin> 
     <plugin> 
      <artifactId>maven-dependency-plugin</artifactId> 
      <version>2.3</version> 
      <configuration> 
       <outputDirectory>${project.build.directory}/lib</outputDirectory> 
      </configuration> 
      <executions> 
       <execution> 
        <phase>package</phase> 
        <goals> 
         <goal>copy-dependencies</goal> 
        </goals> 
       </execution> 
      </executions> 
     </plugin>

确保目标目录/ lib中存在。

这是我的解决方案，希望它对您有所帮助。将以下内容添加到您的文件夹pom.xml

  <plugin> 
      <groupId>org.scala-tools</groupId> 
      <artifactId>maven-scala-plugin</artifactId> 
      <version>2.15.2</version> 
      <executions> 
       <execution> 
        <id>scala-compile-first</id> 
        <goals> 
         <goal>compile</goal> 
        </goals> 
        <configuration> 
         <includes> 
          <include>**/*.scala</include> 
         </includes> 
        </configuration> 
       </execution> 
       <execution> 
        <id>scala-test-compile</id> 
        <goals> 
         <goal>testCompile</goal> 
        </goals> 
       </execution> 
      </executions> 
     </plugin> 
     <plugin> 
      <groupId>org.apache.maven.plugins</groupId> 
      <artifactId>maven-shade-plugin</artifactId> 
      <executions>

          </transformer> 
          <transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">

      </executions> 
     </plugin>
