Adding multiple jars to classpath on commandline

Question

I'm running Ubuntu and want to execute a Java file from terminal by including multiple jar files.

All my jars are included in tha jar folder.

I tried

javac -cp jar/A.jar: jar/B.jar: jar/C.jar: jar/D.jar MyFile.java

I get below error.

javac: invalid flag: jar/B.jar:
Usage: javac <options> <source files>
use -help for a list of possible option

Can anyone guide how to use multiple jars in classpath ?

Solution

Remove the spaces from the classpath and add the current path

javac -cp jar/A.jar:jar/B.jar:jar/C.jar:jar/D.jar:. MyFile.java

Since Java 6 you can use classpath wilcards

javac -cp jar/*:. MyFile.java

and what about if I have to execute the classfile??

The same classpath will work for the JVM

Thanks. Works like a magic.

Specifying application specific jars on system level is not a way to go. This is why startup scripts exist which are often a mess, but more flexible.

What if I want to include a jar and another custom class in the same directory as my Main.java file? I tried javac -classpath ./guava-18.0.jar:. Main.java but it does not find the custom class.

try javac -classpath ./guava-18.0.jar:. *.java
