提问by Dattaprasad Patil
I have a program which is located in
我有一个程序位于
say
说
$A430CLASS/com.airbus.adcsip.batch.GlobalReportBatch
$A430CLASS is the path where my class file is present.
$A430CLASS 是我的类文件所在的路径。
i want to run it through shell script so i entered following command :
我想通过 shell 脚本运行它，所以我输入了以下命令：
java -classpath $A430CLASS/com.airbus.adcsip.batch.GlobalReportBatch $A430CONF/batch.properties
$A430CONF is the path where the batch.properties file is present.
GlobalReportBatch is my class file nameAs you can see i want to pass this batch.properties file as argument to my java program. but when i run my script it tries to replace "." in batch.props file to "/" it gives me NoClassDefFounderror.
$A430CONF 是 batch.properties 文件所在的路径。GlobalReportBatch 是我的类文件名如您所见，我想将此 batch.properties 文件作为参数传递给我的 java 程序。但是当我运行我的脚本时，它会尝试替换“.” 在 batch.props 文件中到“/”它给了我NoClassDefFound错误。

What you put after the -classpathoption must be a list of directories and JAR files, separated by :(on Unix-like operating systems) or ;(on Windows).
您在-classpath选项后面放置的必须是目录和 JAR 文件的列表，以:（在类 Unix 操作系统上）或;（在 Windows 上）分隔。
Look at what you are passing:
看看你通过的是什么：
-classpath $A430CLASS/com.airbus.adcsip.batch.GlobalReportBatch
-classpath $A430CLASS/com.airbus.adcsip.batch.GlobalReportBatch
Remove the slash /between $A430CLASSand your class name; replace it by a space:
删除和你的类名/之间的斜线$A430CLASS；用空格替换它：
-classpath $A430CLASS com.airbus.adcsip.batch.GlobalReportBatch
-classpath $A430CLASS com.airbus.adcsip.batch.GlobalReportBatch
So the entire line becomes:
所以整行变成：
java -classpath $A430CLASS com.airbus.adcsip.batch.GlobalReportBatch $A430CONF/batch.properties
