我在eclipse环境中打开了一个包含build.xml和ivy.xml的项目。 在我应用Run As ..> Ant通过右键单击build.xml构建后,我遇到了这个错误:
BUILD FAILED
Target "retrieve" does not exist in the project "aaa". It is used from target "compile".
我的build.xml文件:

此部分发生错误:
我把它改成了
<target name="compile" description="Compiles source code">
但它显示另一个错误:
Buildfile: D:\eclipse workspace\WOE\build.xml
compile:
[mkdir] Created dir: D:\eclipse workspace\WOE\build\classes
[javac] D:\eclipse workspace\WOE\build.xml:38: warning: 'includeantruntime' was not set, defaulting to build.sysclasspath=last; set to false for repeatable builds
[javac] Compiling 42 source files to D:\eclipse workspace\WOE\build\classes
BUILD FAILED
D:\eclipse workspace\WOE\build.xml:38: D:\eclipse workspace\WOE\lib\default does not exist.

我该怎么办? eclipse环境有什么问题吗?(我在Eclipse环境中没有任何ant插件等),如果有的话,我应该在eclipse中使用哪个插件来正确打开这样的项目?
请帮帮我。 感谢

错误在于:
<target name="compile" depends="retrieve"
使用名称声明目标&#39;检索&#39;或删除依赖项。

这是通过从另一个构建文件进行copy-n-pasting创建的构建文件吗?
你有一个编译目标,它取决于另一个名为&#34; retrieve&#34;
的不存在的目标 <target name="compile" depends="retrieve" description="Compiles source code">
<mkdir dir="${dir.classes}"/>
<javac destdir="${dir.classes}"
debug="true"
target="1.6">
<classpath refid="classpath"/>
<src path="${dir.src}"/>
</javac>
</target>
当使用常春藤时,让第一方解析(必要时下载)第三方jar依赖的目标非常普遍。这是编译代码所必需的。
构建的以下部分引发了第二个错误:
<path id="classpath">
<fileset dir="${dir.lib}" includes="*.jar"/>
<fileset dir="${dir.ivy.lib}/default" includes="*.jar"/>
<!--<pathelement path="${dir.repos}/edu.stanford/BaselineNLProcessor/521/jars/baseline-nlprocessor-2010-06-22-521.jar" />-->
</path>
代码期望在 $ {dir.ivy.lib} / default 目录中找到jar。据推测,这可能是缺少检索任务的一部分。
希望这有帮助。
