manifest-merger fails with "FeatureName must follow"

[Hanmac]

[ERROR] Failed to execute goal com.simpligility.maven.plugins:android-maven-plugin:4.6.0:manifest-merger (update-manifest) on project forge-gui-android: Execution update-manifest of goal com.simpligility.maven.plugins:android-maven-plugin:4.6.0:manifest-merger failed: FeatureName must follow [a-zA-Z0-9][a-zA-Z0-9_]* regex, found -> [Help 1]

there is the code:

android-maven-plugin/src/main/java/com/simpligility/maven/plugins/android/standalonemojos/ManifestMergerMojo.java

Lines 371 to 380 in acaf0ee

	builder.mergeManifestsForApplication(
	androidManifestFile, // mainManifest
	new ArrayList<File>(), // manifestOverlays
	manifestDependencies, // libraries
	"", // packageOverride
	versionCode, // versionCode
	parsedVersionName, // versionName
	minSdkVersion, // minSdkVersion
	targetSdkVersion, // targetSdkVersion
	null, // maxSdkVersion

see this change in the android tools?

I don't know exactly what the featureName should be or if it should be null
