Hesitate to contact us ( you use Juicer in your research, please cite: If you have any difficulties using Juicer, please do not If you are interested in running Juicer in the cloud, you may want to check out the dockerized version The main repository on Github is now focused on the Juicer 2.0 release and is under active development. The beta release for Juicer version 1.6 can be accessed via the Github Release. In thisĭistribution, we include the pipeline for generating Hi-C maps from fastq rawĭata files and command line tools for feature annotation on the Hi-C maps. Juicer is a platform for analyzing kilobase resolution Hi-C data. If you encounter any bugs, please let us know.ĮNCODE's Hi-C uniform processing pipeline based on Juicer can be found here. If you clone the Juicer repo directly from Github, it will clone Juicer 2, which is under active development.

It says that a class does not implement a certain interface.To access Juicer 1.6 (last stable release), please see the Github Release. Take for example this stack trace: :Ĭlass does not implement the requested (TestServlet.java:19) One reason is that the stack traces for classpath problems have a lot of information missing that is needed to troubleshoot the problem.

a class is not visible where it should beīut if it's that simple, then why are classpath problems so hard to debug? Jar Hell stack traces are incomplete.In the end, the common root causes for Jar Hell problems are: It turns out that Jar Hell problems are simpler than what they look, and only a few concepts are needed to solve them. The only real way to solve them is to really understand what is going on, but where to start? These type of problems are hard to approach via trial and error. Let's try to save us some hair and get to the bottom of this. We developers tend to find these problems early and often, and this is the usual response:

They can also happen at the IDE level, and become a source of reduced productivity.

Simple strategy for avoiding classpath problemsĬlasspath problems can be time-consuming to debug, and tend to happen at the worst possible times and places: before releases, and often in environments where there is little to no access by the development team.Class loader priority: Parent First vs Parent Last.We will see why Maven cannot (always) prevent classpath duplicates, and also: In this post we will go through the root causes of these problems, and see how a minimal tool ( JHades) can help solving them quickly. Some of the hardest problems a Java Developer will ever have to face are classpath errors: ClassNotFoundException, NoClassDefFoundError, Jar Hell, Xerces Hell and company.
