本文介绍了如何使用Maven在子文件夹(如Eclipse)中构建包含所需库的jar的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
在Eclipse中,您可以通过执行以下操作在相邻的子文件夹中创建具有所需依赖项的项目jar ...
In Eclipse, you can create a project jar with its required dependencies in an adjacent sub-folder by doing ...
-
Export-> Java-> Runnable JAR file
Export->Java->Runnable JAR file
选择库处理选项:将所需的库复制到生成的JAR旁边的子文件夹中
Select Library handling option: Copy required libraries into a sub-folder next to the generated JAR
有没有办法用Maven程序集插件做到这一点?或者是否有另一个更适合此任务的Maven插件?
Is there a way to do this with the Maven assembly plugin? Or is there another Maven plugin that would be more appropriate for this task?
谢谢!
推荐答案
是的,您可以使用程序集插件。
pom.xml:
yes you can use assembly plugin. pom.xml:
<build>
<!-- final name set the jar name, if left it
will give defualt "${artifactId}-${version}" -->
<finalName>jar final name</finalName>

<!-- compiler plug in -->
<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.6</source>
<target>1.6</target>
</configuration>
</plugin>
<!-- assembly plugin -->
<!-- the assembly plugin is used to define your
final deploy output (jar, zip, dir, war, etc..)-->
<plugin>

<!-- to create a class path to your
dependecies you have to fill true in this field-->
<addClasspath>true</addClasspath>
<!-- if you put your dependencySet/outputDirectory
in the assembly file is in a specific folder (lib for example),
you need to add classpathPrefix-->
<classpathPrefix>lib/</classpathPrefix>
<!-- if you defined your dependencySet/outputFileNameMapping
in the assembly, instead of using the classpathPrefix,
you should use customClasspathLayout,
add the classpathPrefix at the begining of the
customClasspathLayout, and then add the pattern of the outputFileNameMapping,
NOTICE YOU NEED TO ADD '$' BEFOR OF EACH '$'.
