外部jar不在构建项目中加载。 NoClassDefFoundError

Question

So, I have exported my project in both Netbeans and Eclipse and when I try to

java -jar myproject.jar

I get this prompt

In my project I have some libraries which are located inside of src in Netbeans and out of src in Eclipse as it should (please correct me if I'm wrong) The libraries are included via:

Java Build Path > Add JARs...

I've done some research and it seems that I have to change my JAVA CLASSPATH or somethng like that but I don't know exactly how to do it.

The project works perfectly when I compile it and run it, but it crashes after I build it into a Jar file.

By the way, if it isn't clear enough I'm on Ubuntu 14.04

Answer 1

You need to create the path for the jar files and pass it on the command line.

Something like this:

ftp_jar=${Utils_home}/bin/ftpClientUtil.jar
net_jar=${Utils_home}/bin/commons-net-3.3.jar
jsch_jar=${Utils_home}/bin/jsch-0.1.51.jar

java -cp .:$jsch_jar:$net_jar:$ftp_jar com.myplace.ftputils.SFTPClientUtil $*

Answer 2

Run your program as:

java -cp .:[path-of-lib1.jar]:[path-of-lib2.jar] -jar myproject.jar

replace [path-of-libX.jar] with actual path of your libraries.
