Let's rename this file to gradle-...

[martin-g]

Yes!
ASF rules require it

[martin-g]

How is the Gradle plugin being released ?
Since it is not a sub-module of the Maven parent pom what steps would be needed to release it with 1.13.0 ?

@frevib @martin-g Is there anything anyone can do to increase the possibility of this being merged?

[martin-g]

I have no idea.
People come and go on this task ...
It seems no one has the time to finish it.

[frevib]

@henrik242 There is one thing blocking the pipeline. Because the code is dated and has quite some accidental complexity, there exist some pipeline issues. I have asked for help in the Slack channel, but no response. I'll ask again.

[martin-g]

Does this automatically use the latest patch version of 8.14 ? I.e. 8.14.3

[martin-g]

Would it be a good idea to use Gradle 9.x ?

[martin-g]

Those are outdated but Dependabot will upgrade them once this PR is merged

[martin-g]

debug leftovers

Now is the moment everyone interested in the Gradle plugin to help out !

[frevib]

The Avro Gradle plugin is now released in beta and available on Maven Central:
https://central.sonatype.com/artifact/eu.eventloopsoftware.avro-gradle-plugin/eu.eventloopsoftware.avro-gradle-plugin.gradle.plugin/versions

Use instructions: https://github.com/frevib/avro/tree/feat/gradle-plugin/lang/java/gradle-plugin

The plugin supports all options and works for AVSC files only, for now​.

I made a test , it works , I had to change few things

previously

plugins {
    id "com.github.davidmc24.gradle.plugin.avro" version "1.9.1"
}

apply plugin: "com.github.davidmc24.gradle.plugin.avro"
dependencies {
    implementation group: 'org.apache.avro', name: 'avro', version: '1.11.4'
}
tasks.register('generateAvro', com.github.davidmc24.gradle.plugin.avro.GenerateAvroJavaTask) {
    stringType = 'String'
    source("src/test/resources/avro")
    outputDir = file("${layout.buildDirectory.asFile.get()}/generated-main-avro-java/")
}

compileJava.source(generateAvro.outputs)

and now

plugins {
    id "eu.eventloopsoftware.avro-gradle-plugin" version "0.0.2"
}
repositories {
    gradlePluginPortal()
}
apply plugin: "eu.eventloopsoftware.avro-gradle-plugin"
dependencies {
    implementation group: 'org.apache.avro', name: 'avro', version: '1.12.1'
}
avro {
    sourceDirectory = "src/test/resources/avro"
    stringType = 'String'
}
compileJava.source(avroGenerateJavaClasses)
