build.xml构建目标时出错

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:

            </packageset>
        </javadoc>
    </target>


</project>

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.

Total time: 328 milliseconds

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

2 个答案:

答案 0 :(得分:1)

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?

第一期

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。

第二期

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。

使用常春藤的工作示例

希望这有帮助。
