导读：在我的 Khatami项目中,我使用maven来管理编译并将结果打包成一个可运行的工件：顶层的可执行shell脚本,bin /包含可执行jar及其依赖的jar.请看我的意思 here. 作为参考,这里是哈特米的 pom.xml 的显着部分： plugin artifactIdmaven-assembly-plugin/artifact

在我的 Khatami项目中,我使用maven来管理编译并将结果打包成一个可运行的工件：顶层的可执行shell脚本,bin /包含可执行jar及其依赖的jar.请看我的意思 here.

作为参考,这里是哈特米的pom.xml的显着部分：

<plugin>
        <artifactId>maven-assembly-plugin</artifactId>
        <configuration>
          <descriptors>
            <descriptor>src/main/assembly/src.xml</descriptor>
          </descriptors>
          <archive>
            <manifest>
              <mainClass>${project.groupId}.Main</mainClass>
            </manifest>
          </archive>
          <descriptorRefs>
            <descriptorRef>jar-with-dependencies</descriptorRef>
          </descriptorRefs>
        </configuration>
      </plugin>

和全src/main/assembly/src.xml：

<assembly>
  <id>dist</id>
  <formats>
    <format>tar.gz</format>
  </formats>
  <dependencySets>
    <dependencySet>
      <outputDirectory>bin</outputDirectory>
    </dependencySet>
  </dependencySets>
  <fileSets>
    <fileSet>
      <directory>src/main/assembly</directory>
      <outputDirectory>/</outputDirectory>
      <includes>
        <include>khatami</include>
      </includes>
      <fileMode>744</fileMode>
      <lineEnding>unix</lineEnding>
      <filtered>true</filtered>
    </fileSet>
  </fileSets>
</assembly>

和汇编尝试：

$mvn clean compile assembly:single

我在哪里有错？

解决方法

相关部分的错误信息是

Error adding file 'com.carepilot.khatami:khatami:jar:1.0-SNAPSHOT' to archive:
/home/blt/projects/com/carepilot/repos/khatami/target/classes isn't a file.

它期待一个文件,它找不到它,因为包的目标没有运行后清理.

如果你做mvn clean编译包装配：单个它会构建成功.

我将添加程序集：单个目标到程序包阶段,这样它将自动构建.

<plugin>
  <artifactId>maven-assembly-plugin</artifactId>
  <executions>
    <execution>
      <phase>package</phase>
      <goals>
        <goal>single</goal>
      </goals>
      <configuration>
        <descriptors>
          <descriptor>src/main/assembly/src.xml</descriptor>
        </descriptors>
        <archive>
          <manifest>
            <mainClass>${project.groupId}.Main</mainClass>
          </manifest>
        </archive>
        <descriptorRefs>
          <descriptorRef>jar-with-dependencies</descriptorRef>
        </descriptorRefs>
      </configuration>
    </execution>
  </executions>
</plugin>

对您可以发布的配置进行上述更改.

mvn clean package

并且装配：单个目标将被自动执行.

更好的方法是使用maven-shade-plugin而不是手动执行此操作.
