When I run my mod from eclipse, it works fine. When I build it, I get a couple of issues.

 

The first is that some deleted folders end up in the resulting jar. Specifically, the examplemod is still present, and a folder I renamed reverts back to an old name. I can delete the example mod folders again and rename it in the jar to resolve the errors that result.

 

When I try to run the jar, I get an invocation target exception,

the line that the error comes from is

 

"this.setMaxDamage(0);"

in the constructor of a class that extends ItemBlock

I cut out most of the classes, but this should be all the relevant code for where the exception occurs

I tried reverting to an earlier forge version from last month, but it changed nothing.

I tried commenting out the method call the stack trace was being thrown on, but it just threw it at the next line instead.

I made a simpler mod with a single crafting recipe and no new blocks and it ran without issue.

 

Could it be an issue with the mappings? Are the ones I'm using actually for 1.8?

Your build.gradle looks totally fine. Have you tried using an earlier version of Forge 1.8? I've been using 1.8-11.14.0.1281-1.8 with those mappings and the jar builds and runs with no issues.

That is exactly the version of forge I rolled back to to test, and I had the same error.

I tried making a smaller version with just the code I posted and it worked fine.

My current theory is that it has something to do with the renamed folder. Does anyone know how gradle can be including deleted folders in the build, or use old folder names?

Run 'gradlew clean', refresh your workspace, then try again.

 

Sometimes the workspace does not register changes you make if you make them in Windows Explorer - for example, if I am browsing a folder and change a texture name, Eclipse still thinks it's the old name until I tell it to refresh. I've never had it affect the actual build, though... worth a try I suppose.
