如何在eclipse中向项目添加antlib声明

Question

我创建了名为"ant "的项目，用eclipse中的迁移工具测试ant。我在eclipse中创建了java项目，并尝试从那里运行"测试"。

"test" in build.xml:

 <!-- Test out deploy and retrieve verbs for package 'mypkg' -->
    <target name="test">
      <!-- Upload the contents of the "mypkg" package -->
      <sf:deploy username="${sf.username}" password="${sf.password}" sessionId="${sf.sessionId}" serverurl="${sf.serverurl}" maxPoll="${sf.maxPoll}" deployRoot="mypkg" rollbackOnError="true"/>
      <mkdir dir="retrieveOutput"/>
      <!-- Retrieve the contents into another directory -->
      <sf:retrieve username="${sf.username}" password="${sf.password}" sessionId="${sf.sessionId}" serverurl="${sf.serverurl}" maxPoll="${sf.maxPoll}" retrieveTarget="unpackaged" packageNames="MyPkg"/>
    </target>

错误:

Buildfile: C:SFworkspacenewanttbuild.xml test:
BUILD FAILED C:SFworkspacenewanttbuild.xml:19: Problem: failed to create task or type antlib:com.salesforce:deploy Cause: The name is undefined.  Action: Check the spelling.  Action: Check that any custom tasks/types have been declared.  Action: Check that any <presetdef>/<macrodef> declarations have taken place. No types or tasks have been defined in this namespace yet
This appears to be an antlib declaration.  Action: Check that the implementing library exists in one of:
        -C:eclipsepluginsorg.apache.ant_1.8.4.v201303080030lib
        -C:UsersUser.antlib
        -a directory added on the command line with the -lib argument

参考我的答案，

1. 在项目的根目录下创建一个lib目录，并将maven-ant-tasks.jar文件放入其中。

2. 在build.xml

   中包含import语句

   <path id="maven-ant-tasks.classpath" path="lib/maven-ant-tasks-2.1.3.jar" />
   <typedef resource="org/apache/maven/artifact/ant/antlib.xml" uri="antlib:org.apache.maven.artifact.ant" classpathref="maven-ant-tasks.classpath" />
