【问题描述】：
我需要在我的战争中使用 XML 到 JSON 库。 我关注了tutorial，解释了项目中需要依赖项。
但是当我在我的 ant build.xml（用于创建战争的文件）中添加以下内容时，Eclipse 抱怨 artifact:dependencies，似乎它不喜欢 :。我有以下错误消息：
元素
artifact:dependencies的前缀artifact未绑定...
<artifact:dependencies filesetId="dependency.fileset"
sourcesFilesetId="sources.dependency.fileset"
javadocFilesetId="javadoc.dependency.fileset"
versionsId="dependency.versions">
<!-- DEPENCIES GO HERE -->
</artifact:dependencies>
有什么想法吗？
更新
我在尝试定义内存中的 pom 时遇到了同样的问题：
<artifact:pom id="mypom" groupId="org.acme" artifactId="project1" version="1.0">
<dependency groupId="junit" artifactId="junit" version="4.1"/>
<dependency groupId="org.codehaus.plexus" artifactId="plexus-utils" version="1.5.5"/>
<license name="apache" url="http://www.apache.org"/>
</artifact:pom>
元素
artifact:pom的前缀artifact未绑定...

我在 ant/lib 中安装了 maven-ant jar 并更改了 build.xml，使其包含工件的定义，但在运行它时出现错误消息。
<project name="test" default="install" xmlns:artifact="antlib:org.apache.maven.artifact.ant">
<artifact:dependencies pathId="dependency.classpath">
<dependency>
<groupId>net.sf.json-lib</groupId>
<artifactId>json-lib</artifactId>
<version>2.3</version>
<type>jar</type>
<classifier>jdk15</classifier>
<scope>compile</scope>
</dependency>
...
Eclipse 给出的错误信息是：
BUILD FAILED
D:\J2EE\workspace\Test\build.xml:3: Problem: failed to create task or type antlib:org.apache.maven.artifact.ant:dependencies
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.
No types or tasks have been defined in this namespace yet
This appears to be an antlib declaration.
Action: Check that the implementing library exists in one of:
-D:\eclipse\plugins\org.apache.ant_1.8.2.v20110505-1300\lib
-C:\Documents and Settings\luc\.ant\lib
-a directory added on the command line with the -lib argument
maven-ant jar 确实存在于-D:\eclipse\plugins\org.apache.ant_1.8.2.v20110505-1300\lib

这是我正在使用的 build.xml 文件。

在我添加所有依赖项之前它运行良好......仍然无法在此处找到 pb。非常欢迎任何帮助。
