java - How do I access a package protected class in Maven build? -

-

some code returns package protected type trying mock. doing using class.forname, maven throws illegalaccesserror now.

here sample:

class<?> itemsupportclasss = class.forname("com.amazonaws.services.dynamodbv2.document.internal.iteratorsupport"); iterator<item> mockiterator = (iterator<item>) createmock(itemsupportclasss); expect(mockiterator.hasnext()).andreturn(false);  itemcollection<queryoutcome> itemcollection = createmock(itemcollection.class); expect(((iterable<item>) itemcollection).iterator()).andreturn(mockiterator);  // , on

when itemcollection.iterator() called, following error:

java.lang.illegalaccesserror: com/amazonaws/services/dynamodbv2/document/internal/iteratorsupport     @ com.amazonaws.services.dynamodbv2.document.itemcollection$$enhancerbycglib$$14504e4e.iterator(<generated>)     @ com.mycom.myclass(myclass.java:77)     @ com.mycom.myclass(myclass.java:230)     @ sun.reflect.nativemethodaccessorimpl.invoke0(native method)     @ sun.reflect.nativemethodaccessorimpl.invoke(nativemethodaccessorimpl.java:62)     @ sun.reflect.delegatingmethodaccessorimpl.invoke(delegatingmethodaccessorimpl.java:43)     @ java.lang.reflect.method.invoke(method.java:483)     @ org.junit.runners.model.frameworkmethod$1.runreflectivecall(frameworkmethod.java:50)     @ org.junit.internal.runners.model.reflectivecallable.run(reflectivecallable.java:12)     @ org.junit.runners.model.frameworkmethod.invokeexplosively(frameworkmethod.java:47)     @ org.junit.internal.runners.statements.invokemethod.evaluate(invokemethod.java:17)     @ org.junit.internal.runners.statements.runbefores.evaluate(runbefores.java:26)     @ org.junit.runners.parentrunner.runleaf(parentrunner.java:325)     @ org.junit.runners.blockjunit4classrunner.runchild(blockjunit4classrunner.java:78)     @ org.junit.runners.blockjunit4classrunner.runchild(blockjunit4classrunner.java:57)     @ org.junit.runners.parentrunner$3.run(parentrunner.java:290)     @ org.junit.runners.parentrunner$1.schedule(parentrunner.java:71)     @ org.junit.runners.parentrunner.runchildren(parentrunner.java:288)     @ org.junit.runners.parentrunner.access$000(parentrunner.java:58)     @ org.junit.runners.parentrunner$2.evaluate(parentrunner.java:268)     @ org.junit.runners.parentrunner.run(parentrunner.java:363)     @ org.apache.maven.surefire.junit4.junit4provider.execute(junit4provider.java:252)     @ org.apache.maven.surefire.junit4.junit4provider.executetestset(junit4provider.java:141)     @ org.apache.maven.surefire.junit4.junit4provider.invoke(junit4provider.java:112)     @ sun.reflect.nativemethodaccessorimpl.invoke0(native method)     @ sun.reflect.nativemethodaccessorimpl.invoke(nativemethodaccessorimpl.java:62)     @ sun.reflect.delegatingmethodaccessorimpl.invoke(delegatingmethodaccessorimpl.java:43)     @ java.lang.reflect.method.invoke(method.java:483)     @ org.apache.maven.surefire.util.reflectionutils.invokemethodwitharray(reflectionutils.java:189)     @ org.apache.maven.surefire.booter.providerfactory$providerproxy.invoke(providerfactory.java:165)     @ org.apache.maven.surefire.booter.providerfactory.invokeprovider(providerfactory.java:85)     @ org.apache.maven.surefire.booter.forkedbooter.runsuitesinprocess(forkedbooter.java:115)     @ org.apache.maven.surefire.booter.forkedbooter.main(forkedbooter.java:75)

of course, root issue dynamo db returns package protected class iterator, can do?

the real problem here trying mock itemcollection , have return real object. way you're going able solve problem, unfortunately, using powermock:

https://code.google.com/p/powermock/wiki/motivation https://code.google.com/p/powermock/wiki/bypassencapsulation

all have do, when using powermockrunner, put package private class in @preparefortest , should handle you. if not enough let me know in comments.
