Android Build failing with Hugo #4
Comments

Hm, nope reverted to b121 and I'm still getting the same error... |
|
oh woah just read into the stacktrace and noticed this only happens when used in conjunction with Hugo, maybe I should file this bug there? cc @JakeWharton |
|
Both do bytecode weaving so it's unsurprising that they clash. |
|
Ah, that makes sense. I originally thought Hugo was just code gen. |
|
The error message suggests that the Is that a hand-written or generated method? If generated, what generates it? Does the method contain lambda expressions? Does the same error happen if you run the application with JDK 8, without Retrolambda, so that it loads the Looking at the parameter list of the method, it looks like generated by AspectJ. Which version of AspectJ are you using? Is that version compatible with Java 8? (AspectJ 1.8.0.M1 mentions Java 8 compatibility.) |
|
That method is generated by Hugo so those would all be great questions for @JakeWharton 😃 I doubt Hugo is compatible with Java 8 at the moment, and if the fix takes some effort this might be worth postponing until Java 8 is formally released. Everything works fine if I don't use Hugo, so I'm alright for now. |

OK, good to know. Maybe you can try to change the AspectJ version that Hugo uses to be AspectJ 1.8.0.M1. I'll close this issue now since it seems to be unrelated to Retrolambda. |

Brigde methods are generated properly in example:

public interface StringBridges extends BridgeParent<String> {
