使用Ant时出现奇怪的错误

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>

当我运行这个时，会出现如下错误:

Buildfile: C:Usersdi_yuworkspacelessCompilerbuild.xml
css.concatenate:
 [echo] cons is done!
lessc:
 [echo] now in compression
 [java] Compiling...      C:Usersdi_yuworkspacelessCompilersrcmainwebappconscons.less
css.concatenate:

BUILD FAILED
Target "precompile-templates" does not exist in the project "compile". 
Total time: 4 seconds

可以看到，它说"预编译模板"目标不存在。然而，我根本没有把这个任务称为任务。我只是从我的build.xml中删除它，并且没有其他与它相关的目标。错误是如何产生的?PS:我使用eclipse的run作为ANT来运行这个build.xml。

Answer 1

从文件中删除不需要的目标后是否更改了要运行的目标?在我看来，运行配置仍然在使用旧的目标。使用

Answer 2

问题是您创建了一个目标"预编译模板"，随后将其删除…而Eclipse正在"记住"现在已经过时的目标。

建议:1)"文件>保存全部"，2)"项目>清洁项目"Run As, Ant build"

看看这是否有效!

Answer 3

实际上，我发现了问题所在。我仍然使用旧的配置来运行build.xml。解决方案如下:

右键单击build.xml
1. 点击"运行为…"然后点击外部配置工具
2. 删除选中的启动配置。
