I have been using Eclipse to start work on a binding which will be making use of Jsoup.

I have created a lib directory in the project where I placed the jsoup-1.11.2.jar file and have added it to the build path under Libraries, Add JARs.
on my Discovery.java I have an import org.jsoup.Jsoup; which the ide is happy with (doesn’t throw an error that it can’t find the class etc.

Although when I try and test I get the following exception thrown:

After tearing my hair out going around in circles through google searches I have decided it is time to throw it out to the brains trust and hope someone can help me out with where I am going wrong.

Seeing as I accidentally seem to have managed to get this thread to the top of some google searches I thought i’d better list what I can remember that I have tried which hasn’t worked for me but has apparently worked for others with similar problems.

Worked for me:
In META-INF/manifest.mf , make sure Bundle-ClassPath includes the jar not just the folder eg.

Bundle-ClassPath: ., libs/jsoup-1.11.2.jar

Didn’t work for me (but may have been needed as it was tried on my path to a solution:

  • Place the .jar in a lib/libs folder at the root of the project
  • Right click on the .jar Build Path > Add to build path (configure build path, Libraries, Add JARs)
  • Build Configuration, Order and Export, tick next to the .jar
  • Refresh after every change, Clean after every change, close/open Eclipse after every change
  • In the pom.xml try adding the dependency (if using maven) eg.

<dependencies> <dependency> <groupId>org.jsoup</groupId> <artifactId>jsoup</artifactId> <version>1.11.2</version> </dependency> </dependencies>

Hope that can help someone out.
