生成可运行的jar并使用Maven在其中包含库 [英] Generate a runnable jar and include libraries in it with Maven
问题描述
我正在尝试使用Maven和Eclipse编译Java项目,但是我尝试了许多在网络上看到的解决方案,但似乎都没有用.我只想构建应用程序,创建一个可运行的jar并包含所需的库.我尝试了maven-dependency或maven-assembly,但是我肯定会错过一些东西,因为每次都会失败.
I'm trying to compile a Java project with Maven and Eclipse but I tried a lot of solutions seen on the web but none of them seem to work. I just want to build the application, create a runnable jar and include the needed libraries. I tried maven-dependency or maven-assembly but I surely miss something because I fail every time.
这是我的pom.xml,可以吗?或者它遗漏了什么东西?
Here is my pom.xml, is it ok or does it miss something?

推荐答案
使用maven-assembly-plugin
生成具有依赖项的可执行jar
Use the maven-assembly-plugin
to generate an executable jar with dependencies
<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<groupId>org.apache.maven.plugins</groupId>
<version>2.4.1</version>
<executions>
<execution>
<id>make-executable-jar-with-dependencies</id>
<phase>package</phase>
<goals>
<goal>single</goal>
</goals>
<configuration>
<archive>
<manifest>
<addClasspath>true</addClasspath>
<mainClass>com.coderplus.sample.MainClass</mainClass>
</manifest>
</archive>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
</configuration>
</execution>
</executions>
</plugin>
它对您不起作用,因为您已在pluginManagement部分中添加了插件执行.应该将pluginManagement用于管理插件的版本和配置.
It's not working for you because ,you have added the plugin execution in the pluginManagement section. pluginManagement is supposed to be used for managing the plugin version and configuration.
构建标记外观的最低版本:
Minimal version of how your build tag should look like :
<build>
<!-- if you have a multimodule project, I will probably manage this in the
parent pom -->
<pluginManagement>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-assembly-plugin</artifactId>
<version>${assembly.version}</version>
</plugin>
</plugins>
