Issue while adding a new rule

[vickyrocky]

Tailor Version: v0.11.1
Platform (Mac/Linux/Windows/CI): windows
Hi ,

I added a new rule inside com.sleekbyte.tailor.listeners as abc.java and wrote unit test file inside com.sleekbyte.tailor.functional and abc.swift inside \src\test\swift\com\sleekbyte\tailor\functional. Also i wrote metadata and registered abc rule inside Rule.java and Message.java but while building i am getting following error:

java.lang.IllegalArgumentException: 4 > 2 at java.util.Arrays.copyOfRange(Arrays.java:3480) at java.util.Arrays.copyOfRange(Arrays.java:3441) at com.sleekbyte.tailor.functional.RuleTest.testRule(RuleTest.java:69) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:50) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:12) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:47) at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:17) at org.junit.internal.runners.statements.RunBefores.evaluate(RunBefores.java:26) at org.junit.internal.runners.statements.RunAfters.evaluate(RunAfters.java:27) at org.junit.runners.ParentRunner.runLeaf(ParentRunner.java:325) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:78) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:57) at org.junit.runners.ParentRunner$3.run(ParentRunner.java:290) at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:71) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:288) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:58) at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:268) at org.junit.runners.ParentRunner.run(ParentRunner.java:363) at org.mockito.internal.runners.SilentJUnitRunner.run(SilentJUnitRunner.java:39) at org.mockito.internal.runners.StrictRunner.run(StrictRunner.java:35) at org.mockito.runners.MockitoJUnitRunner.run(MockitoJUnitRunner.java:104) at org.gradle.api.internal.tasks.testing.junit.JUnitTestClassExecutor.runTestClass(JUnitTestClassExecutor.java:106) at org.gradle.api.internal.tasks.testing.junit.JUnitTestClassExecutor.execute(JUnitTestClassExecutor.java:58) at org.gradle.api.internal.tasks.testing.junit.JUnitTestClassExecutor.execute(JUnitTestClassExecutor.java:38) at org.gradle.api.internal.tasks.testing.junit.AbstractJUnitTestClassProcessor.processTestClass(AbstractJUnitTestClassProcessor.java:66) at org.gradle.api.internal.tasks.testing.SuiteTestClassProcessor.processTestClass(SuiteTestClassProcessor.java:51) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at org.gradle.internal.dispatch.ReflectionDispatch.dispatch(ReflectionDispatch.java:35) at org.gradle.internal.dispatch.ReflectionDispatch.dispatch(ReflectionDispatch.java:24) at org.gradle.internal.dispatch.ContextClassLoaderDispatch.dispatch(ContextClassLoaderDispatch.java:32) at org.gradle.internal.dispatch.ProxyDispatchAdapter$DispatchingInvocationHandler.invoke(ProxyDispatchAdapter.java:93) at com.sun.proxy.$Proxy2.processTestClass(Unknown Source) at org.gradle.api.internal.tasks.testing.worker.TestWorker.processTestClass(TestWorker.java:117) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at org.gradle.internal.dispatch.ReflectionDispatch.dispatch(ReflectionDispatch.java:35) at org.gradle.internal.dispatch.ReflectionDispatch.dispatch(ReflectionDispatch.java:24) at org.gradle.internal.remote.internal.hub.MessageHubBackedObjectConnection$DispatchWrapper.dispatch(MessageHubBackedObjectConnection.java:155) at org.gradle.internal.remote.internal.hub.MessageHubBackedObjectConnection$DispatchWrapper.dispatch(MessageHubBackedObjectConnection.java:137) at org.gradle.internal.remote.internal.hub.MessageHub$Handler.run(MessageHub.java:404) at org.gradle.internal.concurrent.ExecutorPolicy$CatchAndRecordFailures.onExecute(ExecutorPolicy.java:63) at org.gradle.internal.concurrent.ManagedExecutorImpl$1.run(ManagedExecutorImpl.java:46) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at org.gradle.internal.concurrent.ThreadFactoryImpl$ManagedThreadRunnable.run(ThreadFactoryImpl.java:55) at java.lang.Thread.run(Thread.java:748)

Any help would be highly appreciated!
Thanks!

According to Arrays, this exception occurs if from > to in the call to copyOfRange() which is likely the call occurring here. From what I would guess without seeing your code, your custom rule is not printing any/enough output, so when the test tries to strip the boilerplate output (file path and summary), there are less lines than expected.

Hi @alykhank ,

Thanks for your response! I got to know that but i was unable to sort it out as there is no proper documentation regarding adding a new rule. So if possible can you please list down steps to introduce new rule that would be very helpful for other people as well. I am listing down the steps which i have figured out for my requirement so if any correction is required please let me know:

**Steps-1:**Added logic file in this directory tailor/src/main/java/com/sleekbyte/tailor/listeners/NoHardcoded.java

Steps-2:Added unit test file in this directory tailor/src/test/java/com/sleekbyte/tailor/functional/NoHardcodedTest.java

Steps-3:Added test swift file in this directory tailor/src/test/swift/com/sleekbyte/tailor/functional/NoHardcodedTest.swift

Steps-4:Added rule message in tailor/src/main/java/com/sleekbyte/tailor/common/Messages.java

Steps-5:Registered rule in tailor/src/main/java/com/sleekbyte/tailor/common/Rules.java

This i have followed and my requirement is that if there is any stringliteral inside the code i have to find and raise the issue.
