html5 checker compilation

Question

I would like to use html5 validator from LiipFunctionalTestBundle in my Symfony2 project. So, I followed instructions on bundle's github page, but I got this error during python build:

IOError: [Errno 2] No such file or directory: './syntax/relaxng/datatype/java/dist/html5-datatypes.jar'

indeed, there is a "dist" folder under that path, but it's empty (no files inside). I also tried to download file from daisy-pipeline, but it's deleted after running python build again

I'm using Java 1.7.0_04 on Ubuntu x64

Answer 1

As noted above:

You need to install JDK, not only JRE. That is because you need java compiler.
