Rewrite Plugin to Kotlin

[aygalinc]

If i use the plugin with android build tools in version 3.3.0 and gradle in 4.10.2, i get a conflict on groovy version.

A current workaround can be to specify manually the groovy version in buildscript dependencies section : dependencies { //Jacoco-Android classpath 'org.codehaus.groovy:groovy-all:2.4.15' classpath ("com.vanniktech:gradle-android-junit-jacoco-plugin:0.14.0-SNAPSHOT") }

The exception is the following :

* Exception is: org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':components:gxma.forum.protocol.coap.udp.adapter.component:jacocoDebug'. at

We should rewrite this plugin in Kotlin.

[vanniktech]

Still an issue? Feel free to take a stab at rewriting the plugin into Kotlin.

[aygalinc]

Not a Kotlin expert (even beginner ) ;)

[nateridderman]

We worked around this by excluding groovy from the plugin. It seems to work fine with the newer version that's included in Gradle 4.10.

classpath ('com.vanniktech:gradle-android-junit-jacoco-plugin:0.13.0') { exclude group: 'org.codehaus.groovy' }

Incidentally the jfrog build-extractor plugin had the same issue.

Rewriting in Kotlin is a good idea. Looks like there's not a lot of code. I'll add it to my list of possibilities, but billable work comes first for me.

[vanniktech]

If someone wants to start this just let me know so I can coordinate that new features won't be added in Groovy that will then be needed to convert to Kotlin again.

[vanniktech]

Just released 0.14.0 which fixes the underlying issue. Anyone who wants to convert the plugin to Kotlin is more than welcome. For now, I'll close this issue though.
