What’s New in IntelliJ IDEA 2025.1 EAP? A Deep Dive into the Latest Features

Early Access Program (EAP) Overview

Early Access Program (EAP) allows users to test pre‑release versions of IntelliJ IDEA before the official launch, providing feedback that improves quality, stability, and bug fixing.

Partial Support for Java 24

IntelliJ IDEA 2025.1 EAP includes partial support for Java 24. To try the new language features, set the project SDK to Oracle OpenJDK 24 and change the language level in Project Structure → Project Settings → Project.

Faster Spring Bean Creation

The new version adds a wizard for creating Spring Beans. Use the New… or Generate… menu to generate a Spring Bean class with the appropriate annotations automatically, eliminating the need to create an empty class manually.

Gradle Daemon Toolchain Support

Starting with Gradle 8.13, IntelliJ IDEA 2025.1 EAP can configure the JVM used by the Gradle Daemon via the IDE settings. The selection in Preferences/Settings → Build Tools → Gradle is synchronized with Gradle’s org.gradle.java.home configuration, preventing Daemon JVM mismatches.

Customizable Debugger Toolbar

Developers can now add or remove actions on the debugger toolbar. Right‑click the kebab menu next to the top pane, choose Add to Debugger Toolbar, and select the desired actions.

Inline Hint Text Pop‑up

When inspecting values that contain markup (e.g., XML input), the IDE now shows a formatted pop‑up instead of a raw string. This behavior, previously limited to Watches, is extended to inline debugging, providing consistent and readable output.
