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，我收到一致的错误:
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.

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>
如果我注释掉，就不会再出现错误。
为了进一步引用，这里是整个错误转储:

最佳答案
Grails 与 Ant 1.8 不兼容 - 您需要使用 1.7.x。
关于grails - ant 的 componentdef 错误，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/4060453/
