Java jars unable to resolve class
提问by Bean
I'm relatively new to Java development...I thought I understood how class path works, but I must be missing something.
我对 Java 开发比较陌生……我以为我了解类路径的工作原理，但我一定遗漏了一些东西。
Using Groovy, I have 2 external classes referenced by imports. When I execute the script, I get "unable to resolve class" errors. I have the jars for these in the same directory as the script. If I un-jar them, the script works, but jar'd up the script does not.
使用 Groovy，我有 2 个由导入引用的外部类。当我执行脚本时，出现“无法解析类”错误。我将这些 jars 放在与脚本相同的目录中。如果我 un-jar 它们，脚本会工作，但 jar 脚本不会。
What am I missing here?
我在这里缺少什么？
EXAMPLE
例子
import org.apache.log4j.Logger
Logger log = Logger.getLogger("ldap_delete")
log.info("This is an informative log entry")
Putting log4j-1.2.17.jar in the same directory as the .groovy script does not work. Setting cp to . does not work. I have to do:
将 log4j-1.2.17.jar 放在与 .groovy 脚本相同的目录中不起作用。将 cp 设置为 . 不起作用。我要做：
groovy -cp log4j-1.2.17.jar myscript.groovy
to get the class to load.
让类加载。

Would need to see the script for your specific problem but in general you need to set the classpath when running a java program if it is dependent upon other jars. Here is an example:
需要查看您的特定问题的脚本，但通常您需要在运行 java 程序时设置类路径，如果它依赖于其他 jars。下面是一个例子：
java -cp /path/to/something.jar;/another/path/else.jar my.package.Program
java -cp /path/to/something.jar;/another/path/else.jar my.package.Program
