How to configure maven:assembly root path in the jar
提问by Dreamer
Here is the pom.xml
这是 pom.xml
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>org.springframework.webflow</groupId>
<artifactId>spring-js-resources-thin</artifactId>
<version>2.2.1.RELEASE</version>
<name>Spring js lib</name>
<description>Spring javascript library without dojo</description>
<build>
<plugins>
<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<version>2.2.1</version>
<configuration>
<descriptors>
<descriptor>src/main/assembly/assembly.xml</descriptor>
</descriptors>
</configuration>
</plugin>
</plugins>
</build>
</project>
and here is the assembly.xml
这是 assembly.xml
<assembly>
<id>js-jar</id>
<formats>
<format>jar</format>
</formats>
<fileSets>
<fileSet>
<directory>src/main/resources/</directory>
<outputDirectory>/</outputDirectory>
<includes>
<include>META-INF/**/*</include>
</includes>
</fileSet>
</fileSets>
</assembly>
The problem is, everytime I open the generated jar file(spring-js-resources-thin-2.2.1.RELEASE-js-jar.jar), the root folder is always named as artifactid-version(spring-js-resources-thin-2.2.1.RELEASE), then the META-INF.
问题是，每次打开生成的jar文件（spring-js-resources-thin-2.2.1.RELEASE-js-jar.jar），根文件夹总是被命名为artifactid-version（spring-js-resources-thin-2.2 .1.RELEASE)，然后是 META-INF。
I wonder there is anyway that I can build the jar file with the file name artifactid-version.jar, but WITHOUT the artifactid-versionin the class path, just like every jar in the maven repository. I think there should be an option or a way to name the <outputDirectory>.
我想知道无论如何我可以使用文件名构建 jar 文件artifactid-version.jar，但没有artifactid-version在类路径中，就像 maven 存储库中的每个 jar 一样。我认为应该有一个选项或方法来命名<outputDirectory>.

You have to tell maven-assembly-plugin not to include the base directory within the archive which can be achieved by using the following:
您必须告诉 maven-assembly-plugin 不要在存档中包含基本目录，这可以通过使用以下内容来实现：
<assembly>
<id>js-jar</id>
<formats>
<format>jar</format>
</formats>
<includeBaseDirectory>false</includeBaseDirectory>
<fileSets>
<fileSet>
<directory>src/main/resources/</directory>
<outputDirectory>.</outputDirectory>
<includes>
<include>META-INF/**/*</include>
</includes>
</fileSet>
</fileSets>
</assembly>
And the suggestion about using maven-jar-plugin is very good, cause it looks a little bit that you are misusing the maven-assembly-plugin.
并且关于使用 maven-jar-plugin 的建议非常好，因为看起来你有点滥用 maven-assembly-plugin。
In the most recent versions of maven-assembly-plugin you should .as the root folder. If you use /you will get a warning.
在 maven-assembly-plugin 的最新版本中，您应该将其.作为根文件夹。如果您使用，/您将收到警告。

Add the element to the assembly like so.
像这样将元素添加到程序集中。
<assembly>
<id>js-jar</id>
<formats>
<format>jar</format>
</formats>
<baseDirectory>myBaseDir</baseDirectory>
<fileSets>
<fileSet>
<directory>src/main/resources/</directory>
<outputDirectory>/</outputDirectory>
<includes>
<include>META-INF/**/*</include>
</includes>
</fileSet>
</fileSets>
</assembly>
If you turn the <includeBaseDirectory>off then your archive won't have any root. So it depends on what you want. I prefer my zip files, for instance, to have a base directory so that it doesn't accidentally pollute a directory your in if you forget to create the dir and cd into it before unzipping. Much more convenient too.
如果您关闭，<includeBaseDirectory>那么您的存档将没有任何根。所以这取决于你想要什么。例如，我更喜欢我的 zip 文件有一个基本目录，这样如果您在解压缩之前忘记创建目录和 cd ，它就不会意外地污染您所在的目录。也方便了很多。
