# ksp

[Alessandro Carnevale]

Hi everyone. I’ve some trouble while creating a ksp android library.
I’d like to create an android library that register a SymbolProcessor , but unfortunately when applying it from an android application project the processor provider couldn’t be loaded.

More details about my configuration.
I have 2 projects: lib (android ksp library) and sample (android application).
lib apply com.android.library plugin and register a processor provider inside the canonical file com.google.devtools.ksp.processing.SymbolProcessorProvider under resources/META-INF.services .
I publish the lib in a local maven repo using gradle publish plugin configured with

android {
  publishing {
    singleVariant("release") {
      withJavadocJar()
      withSourcesJar()
    }
  }
}
...
publishing {
  publications {
    register<MavenPublication>("release") {
      groupId = "foo.bar"
      artifactId = "tar"
      version = "1.0"

      afterEvaluate {
        from(components["release"])
      }
      ...

sample consumes it as usual

implementation("foo.bar:tar:1.0")
ksp("foo.bar:tar:1.0")

When launching kspReleaseKotlin or kspDebugKotlin task, this error arises:

e: [ksp] No providers found in processor classpath.

indeed in the jar published in my local maven repository, the file com.google.devtools.ksp.processing.SymbolProcessorProvider is not present.

If I transform lib as a jvm library, everything works right - and the com.google.devtools.ksp.processing.SymbolProcessorProvider is present in the published jar file.

How can I correctly ship the com.google.devtools.ksp.processing.SymbolProcessorProvider inside my lib android library? Or there is another way to define which processor provider ksp must use, and get rid of that file?

processors must be pure jvm libraries, not android libraries
