This version is not published, You can use the 3.2.6 version.

[wu-sheng]

     @Override public ElementMatcher<MethodDescription> getConstructorMatcher() {
             return takesArguments(OkHttpClient.class, Request.class, boolean.class);
      }

@peng-yongsheng Your codes trigger this bug. You can't use the real Class, the right way is using org.apache.skywalking.apm.agent.core.plugin.bytebuddy.takesArgumentWithType.

@myoss This is an undetected bug.

[wu-sheng]

This version is not published, You can use the 3.2.6 version.

@myoss , But still @ascrutae is saying the right things. Tag/Release 3.2.6 is the right choice to use. Maybe you can't find it for now, because ASF INFRA make some mistakes about setting this repo. Please wait one or two days, I suppose.

[wu-sheng]

@myoss Please check this: #676 . @ascrutae is already trying to fix this.

[myoss]

it's ok

[myoss]

@ascrutae Tag/Release 3.2.6 has the same error

[wu-sheng]

@myoss Yes, it does. #676 has been merged. This issue will be solved in 5.0.0-alpha
