问题
I'm using Tomcat7 , jdk 1.7.0_55 & eclipse, when I trying to compile the entire project(Java Code) using COMMAND PROMPT, its showing Error Like javac: invalid flag: D:\COMPILE\lib\activation-1.1.jar. The given below steps are followed to compile the code.
Step.1: dir *.java /s /b > FilesList.txt
Step.2: javac @FilesList.txt -d compiledCode -cp D:\COMPILE\lib\*.jar
After run the Step.2 command its showing Error.so I removed the error jar file from my lib folder & run the command but its showing same error with another jar.
Note: I Already have ANT build.xml but I want to compile the project through COMMAND PROMPT.
回答1:
The lib*.jar gets expanded by the command shell. You need to avoid that by using quotes.
***** -cp "D:\COMPILE\lib\*" *****
The argument to -cp is a single path list (like $PATH, not multiple arguments with one path each). Multiple files can be separated by : (or ; on Windows)
