永久地，通过在系统级上设置CLASSPATH环境变量来实现。
这个方法将在CLASSPATH上查找特*文件，因此有必要将包含该文件的目录放到类路径中。
Permanently by setting the CLASSPATH environment variable at the system level.

必须根据您的环境修改CLPHOME和CLASSPATH。
Jester与IDE的集成不是特别好(或者根本不好)，所以要让测试通过，重要的是正确设置CLASSPATH和目录。
While this seems convenient, it is also a long-term mistake akin to adding directories to the CLASSPATH environment variable.
这看起来很方便，实际上它与向CLASSPATH环境变量添加目录一样，存在长远的潜在问题。
