-=== IDE setup (IntelliJ)
-
-No special steps are needed to open Spring Security in IntelliJ.
-
-=== IDE setup (Eclipse and VS Code)
-
-To work in Eclipse or VS Code, first generate Eclipse metadata so you can import the project into Eclipse or VS Code:
-
-[indent=0]
-----
-./gradlew cleanEclipse eclipse
-----
-
-If you have not built the project yet, run `./gradlew publishToMavenLocal` first so dependencies are resolved.
-
-*VS Code:* Open the repository root as a folder. The repository includes `.vscode/settings.json` which disables automatic Gradle import so that the generated Eclipse metadata (`.classpath`, `.project`) is used. Do not use the Gradle for Java extension to import the project.
-
-*Eclipse:* File → Import → General → Existing Projects into Workspace, then select the repository root.
-
-The build uses a custom Eclipse plugin to work around Gradle dependency cycles that confuse IDE metadata generation. You may see Eclipse warnings about `xml-apis` from some test dependencies; those are excluded in the build and can be ignored.
