[6.5 RC1] UberJar supports Single Jar file?


i’ve a simple question around the topic of the UberJar feature. Is it possible to create one jar file that includes FE and middleware, just like in SingleWarDeployment?

In the corresponding gradle task it does not look like it is supported (yet?), but i just wanted to ask.

The reason is that i would use the uber jar as the deployment unit to heroku. The alternative would be to use two process types within one dyno, that may be also possible (although not sure if this works in free mode)


Hi Mario,

It’s not supported in 6.5 but we are going to implement it in 6.6.
