Java maven程序集插件MojoExecutionException，dependencySet作为outputDirectory

在我的项目中，我使用maven管理编译并将结果打包成可运行工件：顶层的可执行shell脚本，

bin/

，包含可执行jar及其依赖jar。请明白我的意思

作为参考，以下是哈塔米作品的突出部分：

和编译尝试：

我在哪里出错？

错误信息的相关部分是

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.

它需要一个文件，但找不到它，因为

包

目标在

清理

后没有运行

如果您执行

mvn clean compile package assembly:single

，它将成功构建

我将把

assembly:single

目标添加到

package

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>

并且将自动执行

assembly:single

目标

<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>

更好的方法是使用，而不是手动操作。

您的问题：

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.

是因为项目工件（com.careppilot.khatami:khatami:jar:1.0-SNAPSHOT）尚未打包，而是程序集的

的一部分。您可以将

false

添加到

以解决问题

如果需要在程序集中包含项目的类文件，可以使用

来包含目录

目标/类

例如：

<assembly>
  <id>dist</id>
  <formats>
    <format>tar.gz</format>
  </formats>
  <dependencySets>
    <dependencySet>
      <useProjectArtifact>false</useProjectArtifact>
      <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>

距离
tar.gz
假的
箱子
src/主/总成
/
哈塔米
744
unix
真的

另一个选项是在

打包后将程序集附加到阶段

编辑：
当在Maven构建设置中启用
解析工作区工件时，我在Eclipse中也看到了这个问题。
您如何运行Maven构建？从命令行或IDE>命令行内部。最后一个代码清单包含相关行，以
$
开头。您是否曾在eclipse中使用过此项目，并使用一些插件将其导入eclipse环境中。这看起来像是maven的配置问题。我曾经遇到过这样的问题，我跟踪到了我的m2eclipse插件。（顺便说一句）不，恐怕不行。我不使用任何IDE。
