Hey all. I've finally got my first arrow-meta plugin to the point where I'm ready to depend on it in other projects. I've tried to copy the structure of the plugins in the `arrow-meta` repo in order to setup a gradle plugin for loading my arrow-meta plugin, and I can build a jar for the gradle plugin fine -- but I'm not entirely sure how to test the result.

Usually for a library I'd use `publishToMavenLocal`, and then use `mavenLocal()` as a repository in some other project to make sure the maven config is working properly. Is it possible to do the same for a gradle plugin? How would I set up maven to publish a gradle plugin?

I tried skimming through the gradle files in the `arrow-meta` repo to see what would be of help, but no luck so far. Can someone point me in the right direction?

Hi <@U02AWGCS3MX>, you can test the plugin either applying the gradle plugin or applying the compiler plugin to the compilation config free compiler args.

without gradle : <https://github.com/arrow-kt/arrow-meta/blob/main/plugins/analysis/example/build.gradle.kts#L37-L44>
with gradle: (outdated plugins) but config is the same <https://github.com/arrow-kt/arrow-meta-examples/blob/main/demos/refined-types-compiler-plugin-demo/build.gradle#L17-L34>

Hi <@U4UGS5FC7>. I think this answers my question as to how to use my plugin -- something like:

```buildscript {
    repositories {
        mavenLocal()
    }
    dependencies {
        classpath "io.github.sintrastes:buildable-kt-gradle-plugin:0.1"
    }
}

...

apply plugin: "io.sintrastes.buildable-kt"```
And it looks like now after setting up the right maven publish config, I can get most of the way there -- but I'm running into an issue:

```java.lang.NullPointerException: inStream parameter is null
        at arrow.meta.plugin.gradle.ArrowMetaGradlePlugin.apply(ArrowMetaGradlePlugin.kt:19)```
It seems like it can't find my `plugin.properties` file for some reason, and I'm not sure why. Source: <https://github.com/Sintrastes/buildable-kt/blob/main/libs/gradle-plugin-commons/src/main/kotlin/arrow/meta/plugin/gradle/ArrowMetaGradlePlugin.kt>

I took this from the arrow-meta repo to try and get my plugin working with a gradle plugin -- but as I look now at this file in the arrow-meta repo today, I see that it has already changed a bit.

Maybe for now it would better for me to just release my plugin jar, and have users manually add the compiler plugin rather than applying the gradle plugin.

Do you have that properties file on your plugin file like other plugins in the arrow meta repo do?

I believe so. It's possible that it's named incorrectly maybe.
