Maven antrun with sequential ant-contrib could not run

Question

我們有一個特殊的例程，用於將子文件夾中的文件分解爲擴展名，這些擴展名將被複制並加密到單個擴展文件中。對於這種特殊的方法，我想使用maven-antrun-plugin，通過dirset進行順序迭代和jar包裝，我們需要庫ant-contrib。

即將發生的插件配置失敗並顯示錯誤。我錯了什麼配置？謝謝。

Answer 1

它看起來像你缺少真實需要declare the ant-contrib tasks的taskdef，讓螞蟻知道他們而言，因此這部分錯誤消息：

Problem: failed to create task or type for 

（這或許會是一個更清晰一點，如果失敗的任務 - 'for' - 被引用）

一種方式來添加的taskdef是插入它for循環前夕：

<target> 
    <taskdef resource="net/sf/antcontrib/antlib.xml" 
      classpathref="maven.plugin.classpath" /> 
    <for param="extension"> 
    ... 

Answer 2

因此，我浪費了至少一個小時才找到下面的錯誤一個小提示...

我用maven3並且如上所述休息，但我必須使用maven.dependency.classpath 代替maven.plugin.classpath ！否則，maven將無法找到contrib任務。希望這可以幫助任何人。

浪費2小時，讀了太多的答案後，這是我需要檢查

http://www.thinkplexx.com/learn/howto/maven2/plugins/could-not-load-definitions-from-resource-antlib-xml-understanding-the-problem-and-fix-worklow

我用這個

<property name="compile_classpath" refid="maven.compile.classpath"/> 
<property name="runtime_classpath" refid="maven.runtime.classpath"/> 
<property name="test_classpath" refid="maven.test.classpath"/> 
<property name="plugin_classpath" refid="maven.plugin.classpath"/> 
<echo message="compile classpath: ${compile_classpath}"/> 
<echo message="runtime classpath: ${runtime_classpath}"/> 
<echo message="test classpath: ${test_classpath}"/> 
<echo message="plugin classpath: ${plugin_classpath}"/> 

印刷所有的行家類路徑，並檢查其類路徑中包含antrib jar文件。所以我從maven.plugin.classpath 更改classpathhref到maven.runtime.classpath。所以我taskdef是

<taskdef resource="net/sf/antcontrib/antcontrib.properties" classpathref="maven.runtime.classpath" />
