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
