GWT : Class 'java.util.concurrent.CompletableFuture' is not present in JRE Emulation INTELLIJ IDEA
I am working on a GWT project in IntelliJ IDEA Ultimate 2023.3.2
All is running fine.
But IntelliJ keeps telling me that java class files are not present in JRE Emulation Library.
Please help :)
Class 'java.util.concurrent.CompletableFuture' is not present in JRE Emulation Library so it cannot be used in client code of 'com.srr.ShopManager' GWT module
Sorry did forget to add source is included from
<dependency>
<groupId>com.ekotrope</groupId>
<artifactId>gwt-completablefuture</artifactId>
<version>1.0.0</version>
</dependency>
Solution
To fix this annoying error just open Settings -> Project Structure -> Facets. In the bottom right corner of popup you'll see a warning message that gwt-user jar are missing (or something else). Just click "Fix" and "Apply".
After this fix there are no error message about JRE emulation.
