Exporting jar and importing to a project in eclipse results NoClassDefFoundError exception?

Yeah , NoClassDefFoundError usually means the classpath problem , especially there are many class loaders. But I think yours is a simple case.

Had a 3rd parties working JAR file in my own project, but I ran into a problem: I needed some customization to do. Forked a repository from Github. Modified the source code Exported the JAR: Left click > Export > Java > JAR file > Default settings Imported the JAR to my own Android project: Left click > Import > File system & Left Click on project > Properties > Java Build Path > Add JARs > OK Now, when I run my program (which was working fine with 3rd parties official JAR) I run into exception on runtime: 11-10 06:22:05.912: E/AndroidRuntime(1125): Caused by: java.lang.

NoClassDefFoundError: org.jsoup. Jsoup When I extract the JAR file, then it contains all the needed class files (including org.jsoup. Jsoup).

NoClassDefFoundError - error reading the class definition. This typically happens when the class in question has static blocks or members which use a Class that's not found by the ClassLoader. Source As I understand, this seems to be some kind of exported JAR classpath problem?

It's a " Java Build Path > Add External JARs" option in my memory . Maybe you can try.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
