ANT脚本将Maven Dependencies的jar包copy到WEB-INF下

ANT脚本将Maven Dependencies的jar包copy到WEB-INF下

系统之前一直用的是maven-artifact-ant-2.0.4-dep.jar，但最近对一些jar包支持不好，运行ant脚本出现以下问题：

[artifact:dependencies] [WARNING] POM for 'ch.qos.logback:logback-classic:pom:0.9.9' is invalid. It will be ignored for artifact resolution. Reason: The POM expression: ${parent.version} could not be evaluated. Reason: ch.qos.logback:logback-classic:jar:${parent.version} references itself.

这样的话这个忽略的jar包就得手动copy了，这样你还得找这个jar包依赖的其他jar包是不是存在。后来在网上google了一下，发现现在都用maven-ant-tasks-2.1.0.jar，然后对build.xml稍作改动，如下即可：

<? xml version="1.0" encoding="UTF-8" ?>
< project  name ="hehe"  default ="maven-jar"  xmlns:artifact ="urn:maven-artifact-ant" >
     < property  file ="build.properties"   />
         < target  name ="maven-jar"  description ="Use Maven2 to manage jars' dependencies" >
         < echo  message ="deleting old jar .. "   />
         < delete  dir ="${web.dir}/WEB-INF/lib"   />
         < copy  todir ="${web.dir}/WEB-INF/lib" >
             < fileset  id ="runtimeFiles"  dir ="lib/mylib" >
                 < include  name ="**/*.jar"   />
             </ fileset >
             < mapper  type ="flatten"   />
         </ copy >
         < echo  message ="Use Maven2 to manage jar."   />
         < typedef  resource ="org/apache/maven/artifact/ant/antlib.xml"  uri ="urn:maven-artifact-ant" >
             < classpath >
                 < pathelement  location ="lib/maven-ant-tasks-2.1.0.jar"   />
             </ classpath >
         </ typedef >

         < artifact:pom  file ="pom.xml"  id ="my.pom"   />

         < artifact:dependencies  pathId ="dependency.classpath"  filesetId ="dependency.fileset"  usescope ="runtime" >
             < pom  refid ="my.pom"   />
         </ artifact:dependencies >

         < copy  todir ="${web.dir}/WEB-INF/lib" >
             < fileset  refid ="dependency.fileset"   />
             < mapper  type ="flatten"   />
         </ copy >
     </ target >
</ project >

这样就OK了
