Mixin 0.8.5
If you only care about the headlines then here's the lowdown on this release:
- Adds module imports for the new module names for Gson and Guava which ship with Minecraft 1.18. This fixes an issue where mixin was failing to load because it imported the old module names.
- Fixes an issue with the AP which was preventing generation of mappings for anonymous classes
- The AP now detects IntelliJ IDEA and disables some warnings in the same way it previously did for Eclipse
- All AP message levels (eg. warning, error) are configurable
Configuring AP Messaging
Improving the behaviour of the AP when running in the IDE also exposed some opportunities to give you, as a developer, more control over the AP's behaviour. Every single error, warning, or informational message generated by the AP is now configurable via the MessageType enum. This means that in addition to the site-specific @SuppressWarnings support defined in SuppressedBy it's now possible to globally control the message level for individual messages.
Message levels can be controlled by their type code, but don't worry, it's not necessary to look up the code in the MessageType enum every time, since controlling the message levels is fully supported by MixinGradle:
To find out the message type code for a particular message being generated by your build, simply specify the showMessageTypes option in the mixin closure:
mixin {
config "mixins.mymod.json"
add sourceSets.main, "mixins.mymod.refmap.json"
// add this line
showMessageTypes = true
}
Now when you run your build, each message will be prefixed with the message type in square brackets:
MixinRegionFileStorage.java:40: warning: [MIXIN_SOFT_TARGET_IS_PUBLIC] Mixin target
net/minecraft/world/level/chunk/storage/RegionFileStorage is public and should be specified in value
@Mixin(targets = "net/minecraft/world/level/chunk/storage/RegionFileStorage")
^
Now that you know the message type code (MIXIN_SOFT_TARGET_IS_PUBLIC) you can define a new level for the message in your mixin closure. Specify a closure for messages as follows:
mixin {
config "mixins.mymod.json"
add sourceSets.main, "mixins.mymod.refmap.json"
showMessageTypes = true
messages {
MIXIN_SOFT_TARGET_IS_PUBLIC = 'error'
}
}
Now when you run your build, the warning has been upgraded to error:
MixinRegionFileStorage.java:40: error: [MIXIN_SOFT_TARGET_IS_PUBLIC] Mixin target
net/minecraft/world/level/chunk/storage/RegionFileStorage is public and must be specified in value
@Mixin(targets = "net/minecraft/world/level/chunk/storage/RegionFileStorage")
^
