Common Questions

Q: Does Manifold support Java 11? 12? 8?

Yes. Manifold fully supports Java 8 - 12. Manifold also fully supports the Java Platform Module System (JPMS). See the Setup Guide for more info.

Q: Manifold is somehow using Java internal APIs to do its magic. Could it break in a future version of Java?

Unlikely. Java internal APIs can change from version to version, however Manifold always adjusts to changes ahead of Java releases. To understand this better consider Manifold currently works with Java versions 8, 9, 10, 11, 12, and soon 13. The internal APIs have changed significantly between all those versions, yet Manifold continues to work and improve along the way.

Q: Is Manifold free?

Yes, Manifold is an open source project available on github freely available for use via Apache License 2.0.

Q: Does Manifold work with Maven? Gradle?

Yes. Using Maven and Gradle with Manifold is simple. Please refer to the Maven and Gradle sections of the Manifold Setup instructions.

Yes. IntelliJ IDEA provides comprehensive support for Manifold. Download the plugin directly from IntelliJ

Q: How do I get the latest Intellij plugin updates?

Links to recently published Manifold articles are available on the Articles page. There is always another article on the way, check back for more.


Q: I updated to the latest Manifold IntelliJ plugin and now IntelliJ is complaining with error messages. What is wrong?

You probably need to update your project dependencies to use the latest manifold release. If your project’s dependencies are out of sync, the plugin tells you which version of manifold you need with in a warning message when you load your project. You can find the latest releases here.

Important: If you are using Maven or Gradle, you must update your build files – do not change the Module dependencies from IntelliJ’s UI. Please refer to the Maven and Gradle sections of the Manifold Setup instructions.

Please let us know if you can’t get it working, we’re happy to help.
