如何使用字节好友来仪器/重新构成内部类别？

目标

我想创建一个插件包装器来嵌入一个Java代码，该代码可以让我在*之前和*在* and*之前用Junit5注释的方法，并以类似的方式处理Junit5扩展名（ExtentWith andwith notation）。

我选择Bytebuddy作为主要仪表库。

我在此处创建了一个GitHub回购： https://github.com/azewewius.com/azewewiusz/bytebuddy_examples 我在哪里更详细的想法。

问题

问题是我无法让仪器在内部阶级工作。我一直得到两个例外：

引起的：java.lang.illegalstateException：未能调用代理公共摘要java.lang.reflect.annotatedElement net.bytebuddy.description.method.methoddescription $ indefinedshape $ axpactutabase $ expautable.getAnnotatedReceivertype（java.lang.object）

先于

由：java.lang.incompatibleclasschangeerror引起 tests.testsetsetwithinnerclasses和 tests.testsetwithinnerclasses $ helperTestFilterEdOutExtendWithInnerClass 在InnerClasses属性上不同意

复制的测试类，就在这里：

- ＆gt;在那里寻找Test2，

它在此转换时失败了：

final Class strippedOffExtendWithAnnotation = filterOutJUnit5ExtendWithAnnotation(
testClass, classLoader );

Class beforeAll = stagedTypeTransform( strippedOffExtendWithAnnotation,
                new ByteBuddy().rebase( strippedOffExtendWithAnnotation,
                                ClassFileLocator.ForClassLoader.of( classLoader ) )
                        .name( testClass.getName() + "BeforeAll" )
                        .method( ElementMatchers
                        .isAnnotatedWith( BeforeAll.class ) )
                        .intercept( MethodDelegation.to( InterceptorForBeforeAllAnnotation.class ) ).make() );

我发现以下是指类似的问题：

，但尚未找到精确的解决方案。

Goal

I would like to create a plug-in wrapper to embed a Java code that will let me enable/disable methods annotated with JUnit5 Before* and After* annotations at runtime as well as handle in similar manner JUnit5 extensions (the ExtendWith annotation).

I chose ByteBuddy as primary instrumentation library.

I created a github repo here: https://github.com/azewiusz/bytebuddy_examples where I describe the idea in more detail.

Question

The problem is that I cannot get instrumentation working for inner classes.
I keep getting two exceptions:

Caused by: java.lang.IllegalStateException: Failed to invoke proxy for
public abstract java.lang.reflect.AnnotatedElement
net.bytebuddy.description.method.MethodDescription$InDefinedShape$AbstractBase$Executable.getAnnotatedReceiverType(java.lang.Object)

preceded by

Caused by: java.lang.IncompatibleClassChangeError
tests.TestSetWithInnerClasses and
tests.TestSetWithInnerClasses$HelperTestFilteredOutExtendWithInnerClass
disagree on InnerClasses attribute

A test class that reproduces is here:
https://github.com/azewiusz/bytebuddy_examples/blob/master/src/test/java/tests/CoreInstrumentationTest.java

-> Look there for test2

It fails at this transformation:

final Class strippedOffExtendWithAnnotation = filterOutJUnit5ExtendWithAnnotation(
testClass, classLoader );

Class beforeAll = stagedTypeTransform( strippedOffExtendWithAnnotation,
                new ByteBuddy().rebase( strippedOffExtendWithAnnotation,
                                ClassFileLocator.ForClassLoader.of( classLoader ) )
                        .name( testClass.getName() + "BeforeAll" )
                        .method( ElementMatchers
                        .isAnnotatedWith( BeforeAll.class ) )
                        .intercept( MethodDelegation.to( InterceptorForBeforeAllAnnotation.class ) ).make() );

I found following that seem to refer to similar problem:
