如何使用Maven创建没有依赖关系的可执行jar? [英] How can I create an executable jar without dependencies using Maven?
问题描述
我想将它打包在一个可执行的jar中以便分发。我需要一个像main.jar这样的可执行文件,并且所有依赖项都在libs / *中.jar
I want to package it not in a single executable jar for distribution. I need an executable to be something like main.jar and all dependencies to be in libs/*.jar
如何在没有预先包含在其中的maven可执行jar的依赖库中?
How can I make maven executable jar without preincluded into it dependencies libraries?
在我怎样才能使用Maven创建一个带有依赖关系的可执行JAR?有一条注释在2010年12月1日10:46 $ b $bAndréAronsen回答,但是那个只是没有t work(未设置sadescriptorRef失败)。
In How can I create an executable JAR with dependencies using Maven? there is a note by answered Dec 1 '10 at 10:46 André Aronsen, but that one simply doesn't work (failed s.a.descriptorRef is not set).
推荐答案
您可以在一定程度上达到此目的。
You can achieve this to a certain extent.
首先,您要创建一个可执行jar ,适当地配置 maven jar插件。
Firstly, you would create an executable jar by configuring maven jar plugin suitably.
然后你将使用maven程序集插件创建一个jar-with-dependencies,不包括你的项目jar 。为此,您将创建一个描述符文件,例如 src / main / assembly / descriptor.xml
,就像这样。
You would then use maven assembly plugin to create a jar-with-dependencies, excluding your project jar. To do this, you would create a descriptor file, say src/main/assembly/descriptor.xml
, like this.
<assembly xmlns="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.0 http://maven.apache.org/xsd/assembly-1.1.0.xsd">
<id>jar-with-dependencies</id>
<formats>
<format>jar</format>
</formats>
<includeBaseDirectory>false</includeBaseDirectory>
<dependencySets>
<dependencySet>
<outputDirectory>/</outputDirectory>
<useProjectArtifact>false</useProjectArtifact>
<unpack>true</unpack>
<scope>runtime</scope>
</dependencySet>
</dependencySets>
</assembly>
在你的项目中使用它。
<project>
[...]
<build>
[...]
<plugins>
<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<version>2.2.1</version>
<configuration>
<descriptors>
<descriptor>src/main/assembly/descriptor.xml</descriptor>
</descriptors>
</configuration>
[...]
</plugin>
</plugins>
</build>
</project>
你最终会得到两个罐子 - 一个是你的项目创建的可执行jar,另一个是罐子由程序集插件创建的依赖项。
You will end up getting two jars - one the executable jar created by your project and the other the jar-with-dependencies created by the assembly plugin.
