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>
<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：

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.
<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.
