Welcome to our annual JVM ecosystem report! This report presents the results of the largest annual survey on the JVM ecosystem, showing results from the survey gathering over 2000 responses in the second half of 2019. We would like to thank everyone who participated and offered their insights on Java and JVM-related topics.

This report is split into six posts:

  1. JVM ecosystem report 2020 – Introduction
  2. 36% of developers switched from Oracle JDK to an alternate OpenJDK distribution, over the last year
  3. 64% of developers report that Java 8 remains the most often used release
  4. Kotlin overtakes Scala and Clojure, to become the 2nd most popular language on the JVM
  5. Spring dominates the Java ecosystem with 60% using it for their main applications
  6. IntelliJ IDEA dominates the IDE market with 62% adoption among JVM developers

We also have a lovely handcrafted pdf report which contains all of this information in one downloadable place.

For this survey, we teamed up with conferences and communities across the JVM ecosystem to reach as many developers as possible. Big shout out to Devoxx, DevNexus, Jfokus, JCrete, Adopt OpenJDK, VirtualJUG and other Java communities for their invaluable help. As a result of this massive effort, an impressive number of developers participated in the survey, giving great insight into the current state of the JVM ecosystem.
