-If you're using JDK 9 or above then you can use the [--release](https://docs.oracle.com/en/java/javase/11/tools/javac.html#GUID-AEEC9F07-CB49-4E96-8BC7-BCC2C7F725C9)
-flag instead of the plugin:
+NOTE: JDK 9+ signatires are [not published](https://github.com/mojohaus/animal-sniffer/issues/62):

+```
+Starting with JDK9+ you can't define a full API signature cause based on the module system you can define your own (limited view on JDK). Apart from that you can use the release configuration in maven-compiler-plugin with JDK9+ to have exactly what animal sniffer offers and that's the reason why there are no JDK9+ signatures.
+```

+To check JDK 9+ compatibility use [--release flag](https://docs.gradle.org/current/userguide/building_java_projects.html#sec:compiling_with_release) instead of plugin
+(or build signatures [manually with maven plugin](https://www.mojohaus.org/animal-sniffer/animal-sniffer-maven-plugin/examples/generating-java-signatures.html)):
 
 ```groovy
 compileJava {
-  options.compilerArgs.addAll(['--release', '7'])

+* To check strong compatibility with some library: you'll need to [generate signatures](https://github.com/xvik/gradle-animalsniffer-plugin/wiki/Buid-project-signature) for this library and
 will be able to use them to check project compatibility (on API level, ofc) with older library versions.
