Maven maven-assembly-plugin jar-with-dependencies从最终jar中排除LICENSE.txt

Question

我正在使用Maven打包单个可执行jar，但我似乎不知道如何才能不将LICENSE.txt和NOTICE.txt文件放入其中。这些文件可以在最终可执行文件.jar中找到，但我的项目目录中没有这样的文件。

我尝试了多种配置，但都不起作用。我现在所处的位置如下：

在我的pom.xml中，我有：

<build>
  <plugins>
      <plugin>
            <artifactId>maven-assembly-plugin</artifactId>
            <version>2.4</version>                
            <configuration>
                <archive>
                    <manifest>
                        <mainClass>main.Main</mainClass>
                    </manifest>
                </archive>
                <excludes>
                    <exclude>README*</exclude>
                    <exclude>LICENSE*</exclude>
                    <exclude>NOTICE*</exclude>
                </excludes>
                <descriptorRefs>
                    <descriptorRef>jar-with-dependencies</descriptorRef>
                </descriptorRefs>
                <appendAssemblyId>false</appendAssemblyId>                    
            </configuration>
            <executions>
                <execution>
                    <id>maven-assembly-plugin</id>
                    <phase>package</phase>
                    <goals>
                        <goal>single</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>

我还尝试在pom.xml内部使用

<descriptors>
    <descriptor>/src/assembly/src.xml</descriptor>
</descriptors>

而不是

                <excludes>
                    <exclude>README*</exclude>
                    <exclude>LICENSE*</exclude>
                    <exclude>NOTICE*</exclude>
                </excludes>

内容为/src/assembly/src.xml：

        <assembly xmlns="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.2"
                  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                  xsi:schemaLocation="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.2 http://maven.apache.org/xsd/assembly-1.1.2.xsd">
            <id>distribution</id>
            <formats>
                <format>jar</format>
            </formats>
            <fileSets>
                <fileSet>
                    <excludes>
                        <exclude>README*</exclude>
                        <exclude>LICENSE*</exclude>
                        <exclude>NOTICE*</exclude>
                    </excludes>
                    <!--useDefaultExcludes>false</useDefaultExcludes-->
                </fileSet>
            </fileSets>
        </assembly>

但是为了这个，我得到了Failed to execute goal org.apache.maven.plugins:maven-assembly-plugin:2.4:single (maven-assembly-plugin) on project DatabaseTaseng: Failed to create assembly: Error creating assembly archive distribution: A zip file cannot include itself -> [Help 1]

我应该如何配置它才能获得没有这些.txt文件的具有依赖关系的单个可执行jar？

我不使用文件集...

我使用这个配置，取自这里：

http://maven.apache.org/plugins/maven-assembly-plugin/examples/single/filtering-some-distribution-files.html

 <assembly xmlns="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.2"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.2   http://maven.apache.org/xsd/assembly-1.1.2.xsd">
     <id>distribution</id>
  <formats>
    <format>jar</format>
  </formats>
  <files>
    <file>
      <source>README.txt</source>
      <outputDirectory>/</outputDirectory>
      <filtered>true</filtered>
    </file>
    <file>
      <source>LICENSE.txt</source>
      <outputDirectory>/</outputDirectory>
    </file>
    <file>
      <source>NOTICE.txt</source>
      <outputDirectory>/</outputDirectory>
      <filtered>true</filtered>
    </file>
  </files>
 </assembly>

此配置应该过滤您在生成输出jar...so时需要的文件，它还应该过滤将生成的文件。

我希望这对你有用...

exclusions标记用于排除jars依赖项。dependencySet标记允许unpackOptions在解压依赖项时包含/排除文件。因此，您的程序集应该如下所示：

<assembly xmlns="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.3"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.3 http://maven.apache.org/xsd/assembly-1.1.3.xsd">
   <!-- TODO: a jarjar format would be better -->
   <id>jar-with-dependencies</id>
   <formats>
      <format>jar</format>
   </formats>
   <includeBaseDirectory>false</includeBaseDirectory>
   <dependencySets>
      <dependencySet>
         <outputDirectory>/</outputDirectory>
         <useProjectArtifact>true</useProjectArtifact>
         <unpack>true</unpack>
         <scope>runtime</scope>
         <unpackOptions>
            <excludes>
               <exclude>**/README.txt</exclude>
            </excludes>
         </unpackOptions>
      </dependencySet>
   </dependencySets>
</assembly>
