| Instructions on how to compile and apply refaster rules to support library |
| |
| 0. Download error-prone and refaster jars |
| http://errorprone.info/docs/refaster will have up to date instructions |
| |
| 1. Compile the refaster rule (in this example IsAtLeastO.java) |
| java -cp /path/to/android.jar:/path/to/support-compat.jar:javac-9-dev-r3297-4.jar:error_prone_refaster-2.0.18.jar com.google.errorprone.refaster.RefasterRuleCompiler IsAtLeastO.java --out `pwd`/myrule.refaster |
| |
| 2. Update build to use the refaster rule |
| Add compiler args to error-prone in SupportLibraryPlugin.groovy |
| '-XepPatchChecks:refaster:/path/to/refaster/myrule.refaster', |
| '-XepPatchLocation:' + project.projectDir |
| |
| 3. Compile support library using the refaster rule |
| ./gradlew assembleErrorProne |
| |
| 4. Apply patches |
| error-prone will produce patch files like "design/error-prone.patch" and to apply them, cd into the |
| directory e.g. "design" and then run: |
| patch -p0 -u -i error-prone.patch |
| |
| 5. Rules have been applied! Celebrate! |
