How to execute jar file with a external dependency using command line on Windows?

Question

I have jar file with manifest in it

    Manifest-Version: 1.0
    Build-Jdk: 1.7.0_67
    Created-By: Apache Maven 3.2.3
    Main-Class: com.company.main.Main
    Archiver-Version: Plexus Archiver

And the jar has compile dependency to external library

compile 'org.apache.commons:commons-lang3:3.3.2'

So I want to execute it comandLine I wrote:

java -cp C:\commons-lang3-3.3.2.jar -jar myJar-1.0.0.jar

But

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/lang3/StringUtils
        at ...

How to add this file on the class path?

PS. If I use the "bad way" and copy-paste commons-lang3-3.3.2.jar in the ...jre7\lib\ext folder. Everything is working.

Answer 1

If you're not using the -jar option then you need to specify the main class to run, as the manifest will not be interrogated:

java -cp C:\commons-lang3-3.3.2.jar;.\myJar-1.0.0.jar com.company.main.Main

The classpath (-cp) option is ignored if using the -jar option (in that case the manifest should reference any other required jars via its classpath directive).

Answer 2

"Bad Way"..? You should never include your jar files inside the java directories.. How do you expect the users of your application to use your jar when they are using the standard java..?

either you can use the command suggested by @tombola82 or you can include the commons-lang jar in your project itself so that you can refer it.
