Error when creating Javadoc - Industrial Craft error

[CJMinecraft]

So I am getting an error every time I build my mod. I am generating a javadoc, deobf, sources and the regular mod jar. The error I get is shown here:

I've been trying to fix this over the past two months. If you need the code (which I highly doubt it), it is found here https://github.com/CJMinecraft01/CJCore

Try to update jdk and/or gradle. On gradle 4.2.1 and jdk 1.8.0u131 there are only two warnings that do not abrupt build:

How exactly do I go about updating gradle?

[Onyn]

Just follow official instructions.

[CJMinecraft]

It's ok, I figured it out after I sent it. I'm updating the mappings but unfortunately, I have to use ForgeGradle-2.2-SNAPSHOT and not ForgeGradle-2.0.2 because that does not support 1.11.2 any more.

I just realised, this still doesn't work, I haven't updated github so when you ran it, it still was not the latest version

Now your project fails to build due to compilation errors. Correct them first and I try one more time.

[CJMinecraft]

The compilation errors come from the Industrial Craft 2 API and I cannot resolve these

[CJMinecraft]

I have managed to fix this by telling gradle to ignore the error

I added this to my build.gradle

allprojects {
    tasks.withType(Javadoc) {
        options.addStringOption('Xdoclint:none', '-quiet')
    }
}
