@NemethNorbert I'm not fond this

First, it doesn't work for more than one patch issue. Second, I have no idea what the patch was. If you look at our other patched files in modules/third-party, we use actual patch files.

I'm OK with using a patch file in build.gradle

See archived/opensocial-portlet/patches/LPS-21488.patch

But we can do it other ways as well. Please consult with @jbalsas and @wincent thx.

Thanks @brianchandotcom, I had similar doubts, but seeing as this is a very old plugin which hasn't changed ever, it felt like the odds of us having to apply more patches is really insignificant compared to the cost of applying patches.

We'll try to work out a different approach.

I pushed this to my fork as a POC of an alternative approach (downloading then patching the jquery.form source), but I am not really a huge fan of it. There are all sorts of annoying obstacles caused by the way Gradle works (caching) and the other build tooling (Babel); for example, to patch the original source, you can't prepare a patch against what's in src and apply it to build/ or classes/, because the whitespace gets damaged on the way through — so that means you have to patch in-place and then you're fighting against the cache.
