killbill-coupon-plugin-demo Plugin fails to start -

[Vivek]

Hi,

I have noticed an error, "Unable to start bundle" (in FileInstall.java:169) when installing the coupon plugin, https://github.com/killbill/killbill-coupon-plugin-demo. I had compiled it with Java 11. I changed permissions of /var/tmp/bundles directory recursively to 777 but still got the same error.

Below, please find the error log:

Hi Vivek,

Looking at the compatibility history, it seems that it would work with 0.22.x and Java 8. I will check internally about this. You can refer to CouponDemoEntitlementPluginApi.java as an example for the entitlement plugin in the meantime. 

Regards

Karan

I tried with killbill version 0.22.31 and Java 8. It worked. Thanks.

Thank you,

Vivek

Hi Karan

Could you provide some pointers on things to play with, so that the coupon plugin can start with the latest killbill version 0.24.x.

Thank you,

Vivek

[Vivek]

I got it to work with the latest killbill. It only required changes to a couple of method signatures.

Thank you,

Vivek

Hi Vicek,

Are you planning on submitting a PR with the fixes?

Yes. Let me move the files from the helloworld plugin to the coupons plugin and then raise a PR.
