Hi there, I've adopted some of my opensource kotlin projects to publish to maven-central using maven-publish and io.codearte.nexus-staging plugin. However, now I'm stuck migrating my newer bits and pieces that use a build.gradle.kts because I still can't wrap my head around how to translate gradle to gradle-kts. Is there a minimalistic example which I could use as template instead?

I’ve done exactly what you’re asking for here: https://github.com/cortinico/kotlin-android-template/pull/31

Specifically with a precompiled script plugin

The authors of these two plugins have combined their effort to create a single one doing everything the two plugins did. I use it here, for example: https://github.com/Ninja-Squad/DbSetup/blob/master/build.gradle.kts.

It’s documented here: https://github.com/gradle-nexus/publish-plugin

Thx for the pointers and the prompt support.

@jbnizet what happened to artefact signing? I thought this is mandatory for central publishing but seems missing in the process. I've followed the migration guide and declared just stagingProfileId but this fails with

> No value has been specified for property 'repository.nexusUrl'.
> No value has been specified for property 'repository.snapshotRepositoryUrl'.

Do you have an idea what could go wrong? I have no clue about the URLs, all I know is my staging-profile-id.

signing is configures in the convention plugin applied to the two subprojects: https://github.com/Ninja-Squad/DbSetup/blob/master/buildSrc/src/main/kotlin/java-library-convention.gradle.kts#L106-L108

[jbnizet]

Regarding your error, it’s hard to explain without seeing your code. Are you sure you applied the new plugin, and removes the two old ones?

[holgerbrandl]

I think I did, feel welcome to have a look yourself https://github.com/holgerbrandl/kalasim/blob/78d746fe9111da5ab86c6d3eb4bbfe7f2335d737/build.gradle.kts#L133

Credentials are stored in ~/.gradle/gradle.properties and seem to be picked up correctly.

[jbnizet]

Don’t create a new repo. Use the built-in sonatype closure, as explained in the README, and shown in my linked example: https://github.com/Ninja-Squad/DbSetup/blob/master/build.gradle.kts

@jbnizet Thanks to your wonderful and generous help, I managed to sign and release it to central https://repo.maven.apache.org/maven2/com/github/holgerbrandl/kalasim/0.6.4/ Thanks a ton!
