在我pom.xml运行"mvn clean install"时,我使用maven-assembly-plugin创建一个可执行的jar-with-dependencies.现在它首先创建不可执行的"name-version.jar",然后创建"name-version-jar-with-dependencies.jar".
我可以以pom.xml某种方式配置,以便它不会创建不可执行的JAR文件吗？
目前我使用<appendAssemblyId> false </ appendAssemblyId>所以它只是覆盖了第一个文件......
我还得到了几个"......已添加,跳过"消息.我可以以某种方式阻止他们吗？
这是我的maven-assembly-plugin定义pom.xml:
<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<version>2.2-beta-5</version>
<configuration>
<appendAssemblyId>false</appendAssemblyId>
<archive>
<manifest>
<mainClass>my.main.class</mainClass>
</manifest>
</archive>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
</configuration>
<executions>
<execution>
<id>make-assembly</id>
<phase>package</phase>
<goals>
<goal>single</goal>
</goals>
</execution>
</executions>
</plugin>

我使用maven-jar-plugin和像这样的maven-assembly-plugin 的单个目标来工作
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-assembly-plugin</artifactId>
<version>3.1.0</version>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>single</goal>
</goals>
<configuration>
<finalName>finalName</finalName>
<archive>
<manifest>
<mainClass>
mainClass
</mainClass>
</manifest>
</archive>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
</configuration>
</execution>
</executions>
</plugin>
无论如何，最重要的是告诉maven不要使用maven-jar-plugin的此配置生成默认的jar
<plugin>
<artifactId>maven-jar-plugin</artifactId>
<version>3.0.2</version>
<executions>
<execution>
<id>default-jar</id>
<phase>none</phase>
</execution>
</executions>
</plugin>
我想我已经知道如何做到这一点。您必须离开jar，否则将丢失编译器和资源复制，以及构建所需的jar所需的所有其他操作。
我的解决方案本质上涉及欺骗Maven，所以我想提防的是，在将来的版本中这很有可能无法正常工作...
<build>
<defaultGoal>install</defaultGoal>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.6</source>
<target>1.6</target>
</configuration>
</plugin>
<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<configuration>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
<finalName>dumpster-diver</finalName>
<appendAssemblyId>false</appendAssemblyId>
<archive>
<manifest>
<mainClass>DumpsterDiver</mainClass>
</manifest>
</archive>
</configuration>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>single</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
<finalName>${project.artifactId}</finalName>
</build>
请注意，在列出的构建配置中，maven-assembly-plugin的finalName和构建本身都匹配。另请注意<appendAssemblyId>false</appendAssemblyId>。如果执行此操作，则生成文件和程序集jar的输出文件名将完全匹配。Maven肯定会警告您，但会将所需的jar放在目标目录和本地存储库中。
这是该项目上的“ mvn clean install”的输出，以及目标目录和本地存储库中的jar上的jar -tvf：

也许我错过了一些关于你的问题的信息，但下面的代码使我成为一个可执行的 jar：这是你正在寻找的吗？
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>2.3.1</version>
<configuration>
<archive>
<manifest>
<addClasspath>true</addClasspath>
<mainClass>some.main.class</mainClass>
</manifest>
</archive>
<finalName>Proj-${project.version}</finalName>
<outputDirectory>target</outputDirectory>
</configuration>
