IntelliJ 2026.2 EAP implements new features:
Better JaCoCo reports support
In the past, the way to open such reports was to open the file via the file selection dialog in the coverage tool window.
Now, you can open the JaCoCo coverage reports using a double click on the file from the project explorer.
Accurate Gradle tests duration
Gradle measures the exact start and end time of every test class. The IDE ignored this data and shown either the sum of child test duration or nothing. This has been fixed.
Global IDE JVM options
In the past, you had to edit .vmoptions files to set extra JVM options to your IDEs.
Now, the IJ_JAVA_OPTIONS environment variable can be used to set JVM options that would be inherited by all JetBrains JVMs (i.e. your IDEs). The syntax is similar to JDK_JAVA_OPTIONS (JDK’s doc).
