NoSuchMethodError after installing mixins

[cookiedragon234]

I've just setup mixins in my project however upon running my mod within my IDE (IntelliJ) it crashes with a nosuchmethod error. This seems to be linked with the guava library not being found I guess? I've cleaned the project multiple times, restarted my IDE and run build and buildNeeded, yet this still happens. I can build the project and run it as a mod in minecraft without any errors however the mixins don't actually apply.

 

I'd really appreciate any help, thanks.

Why do you need mixins anyway?

Events only get you so far. Currently I'm trying to add custom events for packet send/recieving by adding mixins to the NetworkManager, but there's plenty more opportunities that mixins will open up.

[DaemonUmbra]

What events do you need?

If they're necessary it's preferred that they get added to Forge so others can use them as well.

Packet Send/Recieve events, multiple people have already requested that they get added here on the forums with negative responses. And its not just that, its that Ill be able to add any events I like without waiting for new forge versions and unsupporting all old versions.

So you want to be able to mess with packets that aren't yours?

Mess is an interesting choice of word, I would say to allow the user to modify/monitor certain packets, for example adding a server tickrate counter to the HUD based on the frequency of server update packets received, or prevent the server from sending rotation packets in order to prevent the annoying rotation rubberbanding that can sometimes happen during lag.

There is no need for coremodding to get packet events to work.

It's not just packet events. And this topic wasn't really asking for advice on whether to use mixins. Me and my team already have a design that relies on mixins. Id really appreciate it if you could give me any advice on why it doesnt seem to be able to find the guava library? Is there a way I can download it manually perhaps?

[cookiedragon234]

Found a fix for anyone else with this issue.

 

In build.gradle change:

dependencies {
	compile("org.spongepowered:mixin:0.7.4-SNAPSHOT")
}

to

dependencies {
	compile("org.spongepowered:mixin:0.7.4-SNAPSHOT") {
        exclude module: 'launchwrapper'
        exclude module: 'guava'
        exclude module: 'gson'
        exclude module: 'commons-io'
    }
}
