java - ANT 问题 : net/sf/antcontrib/antcontrib. 属性

Question

我正在尝试将软件安装到我的 Debian Lenny 服务器上。具体来说，Capture-HPC。我已经设置了 VMWare 服务器以及所有先决条件。当我在目录中运行 ant 时，出现以下错误:

[taskdef] Could not load definitions from resource net/sf/antcontrib/antcontrib.properties. It could not be found.

有人知道是什么原因造成的吗？有关我的 ant 安装的详细信息如下:

Apache Ant version 1.7.0 compiled on April 29 2008
Buildfile: build.xml
Detected Java version: 1.6 in: /usr/lib/jvm/java-6-sun-1.6.0.20/jre
Detected OS: Linux

还有 build.xml 文件。 . .

Answer 1

此错误消息表明您正在尝试加载非核心任务，但进一步定义该任务的资源不存在(或不在预期的位置)。

查看安装说明here .

你可以

1. 找到/下载 ant-contrib jar 并将其放入您的 ant 安装中(根据上面链接中的选项 1)；或
2. 修改您的 ant 文件(根据上面链接中的选项 2)以将 ant-contrib jar 包含在嵌套的类路径中。
