How do I put the entire lib directory (including all subdirectories) on the classpath using Ant?
提问by mhaller
I'm not sure this is the problem, but it looks like it might be the case. I'm getting build errors telling me that certain packages don't exist. These packages are packages that exist in .jar files within my lib directory. Any other packages within my java source files that I'm compiling and copying to the classes directory are working just fine. Here are some of the basics of my Ant build script related to this issue:
我不确定这是问题所在，但看起来可能是这样。我收到构建错误，告诉我某些包不存在。这些包是存在于我的 lib 目录中的 .jar 文件中的包。我正在编译并复制到 classes 目录的 java 源文件中的任何其他包都可以正常工作。以下是与此问题相关的 Ant 构建脚本的一些基础知识：
