Question

这是我使用ant。

的build.xml

<?xml version="1.0" encoding="UTF-8"?>
<project name="compile" default="css.concatenate" basedir=".">
<property name="charset" value="utf-8"/>

<!-- compile LESS -->

<target name="css.concatenate">
    <concat destfile="${basedir}/src/main/webapp/cons/cons.less">
        <fileset dir="${basedir}/src/main/webapp/less">
            <include name="*.less"/>
        </fileset>
    </concat>
    <echo>cons is done!</echo>
</target>

<target name="lessc" depends="css.concatenate">
    <echo>now in compression</echo>
    <java classname="CpLess" fork="true">
        <arg value="${basedir}/src/main/webapp/cons"/><!-- input folder that contains less file -->
        <arg value="${basedir}/src/main/webapp/css"/><!-- output folder -->
        <classpath>
            <pathelement location="${basedir}/lib/commons-logging.jar"/>
            <pathelement location="${basedir}/lib/js.jar"/>
            <pathelement location="${basedir}/lib/lesscss-engine.jar"/>
            <pathelement location="${basedir}/lib/yuicompressor.jar"/>
            <pathelement location="${basedir}/lib/zkjszips.jar"/>
            <pathelement location="${basedir}/lib/zkless.jar"/>
            <pathelement location="${basedir}/lib/zul.jar"/> <!-- only needed if using _zkmixins.less -->
        </classpath>
    </java>
</target>

<target name="rename" depends="lessc">
    <echo>renaming...</echo>
    <rename src="${basedir}/src/main/webapp/css/cons.css.dsp" dest="${basedir}/src/main/webapp/css/core.css"/>
    <delete file="${basedir}/src/main/webapp/css/cons.css.dsp.src"/>
    <echo>rename done</echo>
</target>


<target name="trasition" >
            <echo> in trasition </echo>

</target>



</project>

当我运行它时，会出现如下错误：

Buildfile: C:\Users\di_yu\workspace\lessCompiler\build.xml
css.concatenate:
 [echo] cons is done!
lessc:
 [echo] now in compression

BUILD FAILED
Target "precompile-templates" does not exist in the project "compile". 

Total time: 4 seconds

如您所见，它表示“预编译模板”目标不存在。但是，我根本没有打电话给这个任务。我只是从我的build.xml中删除它，并没有其他与之相关的目标。错误是怎么来的？ PS：我使用eclipse作为ANT来运行这个build.xml。

Answer 1

从文件中删除不必要的目标后，是否更改了要运行的目标？在我看来，运行配置仍在使用旧目标。使用

Answer 2

问题是你创建了一个目标“precompile-templates”，你随后将其删除了......而Eclipse正在“记住”现在过时的目标。

建议： 1）“文件＆gt;全部保存”，2）“项目＆gt;清理项目”3）“运行方式，Ant构建”

看看是否有效！

Answer 3

实际上，我发现了问题所在。我仍然使用旧配置来运行build.xml。解决方案是这样的：

右键单击build.xml
点击＆＃39;运行为...＆＃39;然后单击外部配置工具
删除所选的启动配置。
