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
