罐是在類路徑，但拒絕工作

我的類路徑是：罐是在類路徑，但拒絕工作

:.:/usr/share/java/*:/usr/share/tomcat7/lib/servlet-api.jar

編輯：

IT也是，如果我有我的類路徑設置爲

:.:/usr/share/java/:/usr/share/tomcat7/lib/servlet-api.jar

不起作用

或

:.:/usr/share/java:/usr/share/tomcat7/lib/servlet-api.jar

我知道該目錄包含了我想用但javac的仍然給我的錯誤類正確的罐子：

javac util/GSpreadsheets.java

如果手動指定的jar，我需要使用-cp它的工作原理，有時。但是，如果使用-cp我必須手動指定每個我想要使用的每個罐子。這是一個痛苦的屁股。

該目錄包含。

在旁邊注意爲什麼代碼塊不遵守換行符？

什麼是命令行？ -classpath不支持通配符，但有一些限制：http://docs.oracle.com/javase/6/docs/technotes/tools/windows/classpath.html – Jayan 2012-03-06 08:22:42

如果您在Linux上運行，請務必逃避通配符，否則你將面臨shell擴展。例如，使用'java -cp lib/\ * com.mycompany.Main' – 2012-03-06 08:29:07

我的命令行只是'javac javafile.java'我將$ CLASSPATH設置爲一個環境變量。我正嘗試在我的命令行中不使用-cp。 – 2012-03-06 16:54:44

您可以使用下面的語法來包含目錄在類路徑中的特定目錄中的所有jar。

export CLASSPATH=$CLASSPATH:$(find $REQUIRED_DIRECTORY -name "*.jar"|tr "\n" ":")

不能在類路徑中使用*。您應該分別指定每個罐子。

罐是在類路徑，但拒絕工作
