gradle hides alot of details such as how the package jars (how does assembly/package include external resources such as dlls?)
also the gradle scala -> java conversion was empty so I retasked kafka core and client modules to regular maven pom.xml I am currently correcting my way thru 100+ compile Scala errors (HINT: I am using suffix .asScala() alot) My feeling is if you spend more than 5 min on something (gradle) with no resolution then you need to try something else so if you email me directly I will send you the pom.xml that I have for the specific kafka module you are working on The end result would be a build to clearly illustrate whats going on and to *not* hide or obfuscate any necessary detailsif the build dependencies need a dependency maven will tell you if you have wrong version of an artifact maven will tell you if maven cant find a resource it will tell you If there are compile errors it will tell youIf you want specific functionality that nobody else has accomplished you can easily write a custom mojo and integrate to <build> *Best Regards* Martin ______________________________________________ > From: mathieu.fenn...@replicon.com > Date: Tue, 23 Aug 2016 06:36:09 -0600 > Subject: Re: Build Issue with Gradle > To: users@kafka.apache.org > > Oh, that's interesting.
