// If you add an external dependency, then do the following:
// 1. Before adding the dependency, run ./gradlew copyJarsToDist.
// 2. Copy checker/dist/checker.jar elsewhere.
// 3. Add the dependency, then run ./gradlew clean copyJarsToDist.
// 4. Unzip both jars and compare the contents.
// 5. Add relocate lines below for the packages.
// 6. Do steps 3-5 until all new classes are in org/checkerframework/.
// Note that string literals are also relocated. Therefore, when the original
// names should be used, e.g. to load the original classes, one needs to work
// around the relocation. When adding a new external dependency, make
// sure no existing string literals are accidentally relocated.
// For an example work-around see NullnessAnnotatedTypeFactory#NONNULL_ALIASES.
// Relocate packages that might conflict with user's classpath.
