this is my build.bp:

java_library_static {

name: "mylib",

srcs: [

"*.java",

"*.kt",

"**/*.java",

"**/*.kt",

],

optimize: {

enabled: false,

},

}

but it yields very strange errors when building, like:

SysProperty.kt:9:16: error: type mismatch: inferred type is java.lang.String! but kotlin.String was expected

return SystemProperties.get(key)

^

SysProperty.kt:9:33: error: cannot access class 'java.lang.String'. Check your module classpath for missing or conflicting dependencies

return SystemProperties.get(key)

^

SysProperty.kt:9:37: error: type mismatch: inferred type is kotlin.String but java.lang.String! was expected

return SystemProperties.get(key)

^

SysProperty.kt:14:16: error: type mismatch: inferred type is java.lang.String! but kotlin.String was expected

return SystemProperties.get(key, def)

^

SysProperty.kt:14:33: error: cannot access class 'java.lang.String'. Check your module classpath for missing or conflicting dependencies

return SystemProperties.get(key, def)

^

SysProperty.kt:14:37: error: type mismatch: inferred type is kotlin.String but java.lang.String! was expected

return SystemProperties.get(key, def)

^

SysProperty.kt:14:42: error: type mismatch: inferred type is kotlin.String but java.lang.String! was expected

return SystemProperties.get(key, def)

^

SysProperty.kt:19:33: error: cannot access class 'java.lang.String'. Check your module classpath for missing or conflicting dependencies

return SystemProperties.set(key, value)

^

TelephonyMgr.kt:11:48: error: cannot access class 'java.lang.Object'. Check your module classpath for missing or conflicting dependencies

getContext().getSystemService(Context.TELEPHONY_SERVICE) as TelephonyManager

^

TelephonyMgr.kt:11:48: error: cannot access class 'java.lang.String'. Check your module classpath for missing or conflicting dependencies

CoreApi.getInstance().getContext().getSystemService(Context.TELEPHONY_SERVICE) as TelephonyManager

It looks like some standard java classes are missing, such as java.lang.String, java.lang.Object, but why?

I'm not sure what's happening here, but a few questions/comments:

What Android version are you using?

srcs: [
"*.java",
"*.kt",
"**/*.java",
"**/*.kt",
],

This will duplicate the list of java and kotlin files in the current directory, since ** will match both the current directory and all subdirectories. I can't see how that would cause this problem, but it's a good thing to clean up.

I build on Android 9 AOSP.

removing the redundant doesn't help, the errors still exist.
