构建 Processing 时找不到 Antlr

这是我构建时的错误http://www.processing.org/：

BUILD FAILED
/opt/processing/build/build.xml:309: The following error occurred while executing this line:
/opt/processing/build/build.xml:365: The following error occurred while executing this line:
/opt/processing/java/build.xml:37: Problem: failed to create task or type antlr
Cause: the class org.apache.tools.ant.taskdefs.optional.ANTLR was not found.
        This looks like one of Ant's optional components.
Action: Check that the appropriate optional JAR exists in
        -/opt/apache-ant-1.9.5/lib
        -/root/.ant/lib
        -a directory added on the command line with the -lib argument

Do not panic, this is a common problem.
The commonest cause is a missing JAR.

This is not a bug; it is a configuration problem

我按照说明操作，将 jar 放在正确的位置。我没有看到任何关于如何在命令行上传递 -lib 的 ant 文档，我甚至尝试通过包管理器安装 antlr，它可以工作，我可以输入 antlr，它会吐出

Antlr parser generator   Version 1.33MR33   1989-2001

我能做些什么？

从 gluegen 包中得到了相同的消息。Google 找到了http://www.java2s.com/Code/Jar/a/Downloadantoptional1531jar.htm仅用于类搜索。安装 ant-optional/ant-optional-1.5.3-1.jar.zip( 608 k) 解决了这个问题（用于下一个）。
