Unable to understand a error from gradle build -Xlint:unchecked - gradle

Question

I got this error while building hibernate using gradle
:hibernate-entitymanager:compileTestJava
/home/jsiddharth/workspace/hibernate-orm-master/hibernate-entitymanager/src/test/java/org/hibernate/jpa/test/criteria/paths/SingularAttributeJoinTest.java:128: error: <anonymous org.hibernate.jpa.test.criteria.paths.SingularAttributeJoinTest$2> is not abstract and does not override abstract method integrate(MetadataImplementor,SessionFactoryImplementor,SessionFactoryServiceRegistry) in Integrator
return new Integrator() {

:hibernate-entitymanager:compileTestJava FAILED
FAILURE: Build failed with an exception.
I assumed that I need to run gradle with the -Xlint options, but turns out, I am doing it wrong. I got this error when I ran
./gradlew eclipse -Xlint:deprecation -Xlint:unchecked Maven settings.xml file did not exist : /home/jsiddharth/.m2/settings.xml
FAILURE: Build failed with an exception.
* What went wrong:
Problem configuring task :eclipse from command line. Unknown command-line option '-X'.
> Unknown command-line option '-X'.
* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.
BUILD FAILED
Total time: 16.185 secs
How do I run my build to ignore the errors ?

As to you question, the -Xlint is a Java compiler option and has nothing to do with Gradle. You can specify these options via GRADLE_OPTS which is how Gradle passes arguments to the JVM.
Specifically: GRADLE_OPTS="-Xlint:deprecation"
Anyway this is not your trouble. Have a look at the error:
SingularAttributeJoinTest$2> is not abstract and does not override abstract method integrate(MetadataImplementor,SessionFactoryImplementor,SessionFactoryServiceRegistry) in Integrator
return new Integrator() {
You have an anonymous class inside SingularAttributeJoinTest which is declared to implement Integrator but fails to implement method integrate and is not declared abstract. This kind of error can't be suppressed by a -Xlint option of course.
