Auto configure pre-commit hooks for a Gradle Spring App

Steps

  1. create a file called "pre-commit" with no extension in the project directory root
  2. add the code from the pre-commit file below into that new file
  3. create a new file called "preCommit.gradle" inside of the root gradle folder
  4. add the code from the preCommit.gradle file below into that new file
  5. add the following line at the end of the build.gradle file:
    • apply from: "$projectDir/gradle/preCommit.gradle"

Now when you run the ./gradlew build command the git pre-commit hook will be automatically setup.

public interface UserRepository extends JpaRepository<User, Long> {
@Query(value = "SELECT * FROM USERS WHERE LASTNAME = ?1",
countQuery = "SELECT count(*) FROM USERS WHERE LASTNAME = ?1",
nativeQuery = true)
Page<User> findByLastname(String lastname, Pageable pageable);
}
