= Spring Security

Spring Security provides security services for the https://docs.spring.io[Spring IO Platform]. Spring Security 6.0 requires Spring 6.0 as
a minimum and also requires Java 17.

For a detailed list of features and access to the latest release, please visit https://spring.io/projects[Spring projects].

== Code of Conduct
Please see our https://github.com/spring-projects/.github/blob/main/CODE_OF_CONDUCT.md[code of conduct]

== Downloading Artifacts
See https://docs.spring.io/spring-security/reference/getting-spring-security.html[Getting Spring Security] for how to obtain Spring Security.

== Documentation
Be sure to read the https://docs.spring.io/spring-security/reference/[Spring Security Reference].
Extensive JavaDoc for the Spring Security code is also available in the https://docs.spring.io/spring-security/site/docs/current/api/[Spring Security API Documentation].

You may also want to check out https://docs.spring.io/spring-security/reference/whats-new.html[what's new in the latest release].

== Quick Start
See https://docs.spring.io/spring-security/reference/servlet/getting-started.html[Hello Spring Security] to get started with a "Hello, World" application.

== Building from Source
Spring Security uses a https://gradle.org[Gradle]-based build system.
In the instructions below, https://vimeo.com/34436402[`./gradlew`] is invoked from the root of the source tree and serves as
a cross-platform, self-contained bootstrap mechanism for the build.

=== Prerequisites
https://docs.github.com/en/get-started/quickstart/set-up-git[Git] and the https://www.oracle.com/java/technologies/downloads/#java17[JDK17 build].

Be sure that your `JAVA_HOME` environment variable points to the `jdk-17` folder extracted from the JDK download.

=== Check out sources
[indent=0]
----
git clone git@github.com:spring-projects/spring-security.git
----

=== Install all `spring-*.jar` into your local Maven repository.

[indent=0]
----
./gradlew publishToMavenLocal
----

=== Compile and test; build all JARs, distribution zips, and docs

[indent=0]
----
./gradlew build
----

The reference docs are not currently included in the distribution zip.
You can build the reference docs for this branch by running the following command:

----
./gradlew :spring-security-docs:antora
----

That command publishes the docs site to the `_docs/build/site_` directory.
The https://github.com/spring-projects/spring-security/tree/docs-build[playbook branch] describes how to build the reference docs in detail.

Discover more commands with `./gradlew tasks`.

=== 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.
