与ant的componentdef错误

标签： grails ant groovy build

我有一个相对较旧的Grails应用程序，它使用ant来构建应用程序。在测试服务器中它构建没有任何问题，但是当我尝试在我的PC上运行它时，我得到一致的错误：

Caused by: jar:file:/C:/ant/apache-ant-1.8.0/lib/ant.jar!/org/apache/tools/ant/antlib.xml:37: Problem: failed to create task or type componentdef
    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.

        at org.apache.tools.ant.taskdefs.Definer.loadAntlib(Definer.java:432)
        ... 63 more

我发现错误发生在构建的以下部分：

<macrodef name="grails">
    <attribute name="script"/>
    <attribute name="args" default="" />
    <sequential>
        <grailsTask script="@{script}" args="@{args}" classpathref="grails.classpath">
            <compileClasspath refid="compile.classpath"/>
            <testClasspath refid="test.classpath"/>
            <runtimeClasspath refid="app.classpath"/>
        </grailsTask>
    </sequential>
</macrodef>

如果我发表评论，则不会再出现错误。

进一步参考，这是整个错误转储：

Grails与Ant 1.8不兼容 - 您需要使用1.7.x。

答案 1 :(得分：2)

我找到了问题的根源。

问题不是Ant的版本，而是Grails和缺少脚本的版本。此应用程序使用的是Grails（版本1.1.1）的弃用版本。

以下代码，我为每个人的便利重新列出，是调用脚本。但是，在此特定应用程序中，脚本已被删除，这导致Grails的构建过程崩溃：

<macrodef name="grails">
<attribute name="script"/>
<attribute name="args" default="" />
<sequential>
    <grailsTask script="@{script}" args="@{args}" classpathref="grails.classpath">
        <compileClasspath refid="compile.classpath"/>
        <testClasspath refid="test.classpath"/>
        <runtimeClasspath refid="app.classpath"/>
    </grailsTask>
</sequential>
</macrodef>

解决方案很简单：将Grails升级到更新的版本，例如1.3.5。在那之后构建工作没有问题，即使缺少一些脚本。

我推测这种新行为允许在脚手架中生成脚本，但同时让开发人员可以自由删除不需要的或不必要的脚本。
