1. 修改pom.xml
pom.xml中设置如下:
<
build
>
< plugins >
< plugin >
< artifactId >maven-assembly-plugin </ artifactId >
< configuration >
<!-- not append assembly id in release file name -->
< appendAssemblyId >false </ appendAssemblyId >
< descriptors >
< descriptor >src/main/assemble/package.xml </ descriptor >
</ descriptors >
</ configuration >
< executions >
< execution >
< id >make-assembly </ id >
< phase >package </ phase >
< goals >
< goal >single </ goal >
</ goals >
</ execution >
</ executions >
</ plugin >
</ plugins >
</ build >
< plugins >
< plugin >
< artifactId >maven-assembly-plugin </ artifactId >
< configuration >
<!-- not append assembly id in release file name -->
< appendAssemblyId >false </ appendAssemblyId >
< descriptors >
< descriptor >src/main/assemble/package.xml </ descriptor >
</ descriptors >
</ configuration >
< executions >
< execution >
< id >make-assembly </ id >
< phase >package </ phase >
< goals >
< goal >single </ goal >
</ goals >
</ execution >
</ executions >
</ plugin >
</ plugins >
</ build >
其中<artifactId>maven-assembly-plugin</artifactId>的maven-assembly-plugin是这个插件的标准命名,在maven2.0.*中带的默认版本是
appendAssemblyId属性控制是否在生成的打包文件的文件名中包含assembly id。
descriptor属性指定maven-assembly-plugin的配置文件,当然我设置的是src/main/assemble/package.xml.容许使用多个,功能强大当然用法也复杂,对于简单情况一个足矣。
execution的设置是为了将maven-assembly-plugin继承到标准的maven打包过程中,这样在运行maven-package时就会执行maven-assembly-plugin的操作,从而实现我们需要的自定义打包。
2. assemble descriptor file
我的src/main/assemble/package.xml内容如下:
<
assembly
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/assembly-1.0.0.xsd" >
< id >package </ id >
< formats >
< format >zip </ format >
</ formats >
< includeBaseDirectory >true </ includeBaseDirectory >
< fileSets >
< fileSet >
< directory >src/main/bin </ directory >
< outputDirectory >/ </ outputDirectory >
</ fileSet >
< fileSet >
< directory >src/main/config </ directory >
< outputDirectory >config </ outputDirectory >
</ fileSet >
</ fileSets >
< dependencySets >
< dependencySet >
< outputDirectory >lib </ outputDirectory >
< scope >runtime </ scope >
</ dependencySet >
</ dependencySets >
</ assembly >
xsi:schemaLocation ="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/assembly-1.0.0.xsd" >
< id >package </ id >
< formats >
< format >zip </ format >
</ formats >
< includeBaseDirectory >true </ includeBaseDirectory >
< fileSets >
< fileSet >
< directory >src/main/bin </ directory >
< outputDirectory >/ </ outputDirectory >
</ fileSet >
< fileSet >
< directory >src/main/config </ directory >
< outputDirectory >config </ outputDirectory >
</ fileSet >
</ fileSets >
< dependencySets >
< dependencySet >
< outputDirectory >lib </ outputDirectory >
< scope >runtime </ scope >
</ dependencySet >
</ dependencySets >
</ assembly >
详细的语法不介绍了,请参考官方指南,有非常详尽的说明: Assembly Descriptor Format reference
简单解释一下:
1) format
format=zip设置打包的最终文件格式为zip.
支持的其他格式还有gz,tar,tar.gz,tar.bz2。
2) fileset
<
fileSet
>
< directory >src/main/bin </ directory >
< outputDirectory >/ </ outputDirectory >
</ fileSet >
< directory >src/main/bin </ directory >
< outputDirectory >/ </ outputDirectory >
</ fileSet >
将src/main/bin目录下的文件打包到根目录(/)下.
<
fileSet
>
< directory >src/main/config </ directory >
< outputDirectory >config </ outputDirectory >
</ fileSet >
< directory >src/main/config </ directory >
< outputDirectory >config </ outputDirectory >
</ fileSet >
将src/main/config目录下的文件打包到config下.
3) dependencySets
<
dependencySet
>
< outputDirectory >lib </ outputDirectory >
< scope >runtime </ scope >
</ dependencySet >
< outputDirectory >lib </ outputDirectory >
< scope >runtime </ scope >
</ dependencySet >
将scope为runtime的依赖包打包到lib目录下。
总结一下,pom.xml中引入maven-assembly-plugin,然后assemble descriptor file按需设置,最后在eclipse中执行Run As -> Maven package,在target目录下就会出现***.zip文件,里面的格式和要求的完全一致。
