executing jar file: Caused by: java.lang.ClassNotFoundException: org.springframework.context.ApplicationContext

I have created a maven project. After I type: mvn clean package everything works fine and I see my jar file inside target. But if I click the file I get the follwing error message:

Exception in thread "main" java.lang.NoClassDefFoundError: org/springframework/c
ontext/ApplicationContext

Could not find the main class: comt.test.Test. Program will exit

I can run the project under Eclipse and works ok, but the jar file doesnt work.

Thanks in advance for your help.

When you build a JAR, it only has your classes in it. It doesn't contain all the other libraries that your project depends on. (Doing that is possible, but it's not common and mostly inadvisable.) To run a class in your JAR that depends on Spring, you have to be sure Spring is on the classpath, either by passing a classpath to the java executable (doesn't work if using the -jar argument) or by putting a "Class-Path" attribute in the JAR's manifest file. Of course, it's not just Spring. You'll have to include a classpath entry for every jar your project depends on.

see another post regarding the same problem you need to create a classPath (the eclipse is dong it automatically for you, and this is why you have no problem ruining the project from the eclipse) for the dependencies (in your case the spring)
