NPE exception trying to build against 2.0.0-rc1
Closed this issue · 2 comments
I'm was trying to switch to the latest version of JSweet and the plugin (2.0.0-rc1) to do some testing with the new features and functionality, but am hitting a null pointer exception when doing so. Below is the full stack trace. Let me know if there's anything other info you'd like or things to try. Thanks

Oops. My fault. I think that' because the verbose variable can be null now so we have to check it.
I have released version 2.0.0-rc1u1, which should fix it, and PR'd the fix.
BTW, an easy workaround for version 2.0.0-rc1 would just be to add the verbose option to your pom (true or false).
