 ### Utility library usage
 
-hawkBit has currently both [guava](https://github.com/google/guava) and [Apache commons lang](https://commons.apache.org/proper/commons-lang/) on the classpath in several of its modules. However, we see introducing too many utility libraries problematic as we force these as transitive dependencies on hawkBit users. We in fact are looking into reducing them in future not adding new ones.

 * use utility functions in general based in the following priority:
   * use utility functions from JDK if feasible
   * use Spring utility classes if feasible
-  * use [Guava](https://github.com/google/guava) if feasible
   * use [Apache commons lang](https://commons.apache.org/proper/commons-lang/) if feasible
 
-Examples:
-
-* Prefer `Arrays.asList(...)` from JDK over Guava's `Lists.newArrayList(...)`
-* Prefer `StringUtils` from Spring over Guava's `Strings` and Apache's `StringUtils`
-
 ### Test documentation
 
 Please document the test cases that you contribute by means of [Allure](https://docs.qameta.io/allure/) annotations and proper test method naming.
