Spring AOT is a process that analyzes your application at build-time and generate an optimized version of it.
It is a mandatory step to run a Spring `ApplicationContext` in a native image.
NOTE: For an overview of GraalVM Native Images support in Spring Boot, check the {spring-boot-reference}/#native-image[reference documentation].
NOTE: For an overview of GraalVM Native Images support in Spring Boot, check the xref:reference:native-image/index.adoc[reference documentation].
The Spring Boot Maven plugin offers goals that can be used to perform AOT processing on both application and test code.
[[aot.processing-applications]]
== Processing Applications
To configure your application to use this feature, add an execution for the `process-aot` goal, as shown in the following example:
[source,xml,indent=0,subs="verbatim,attributes",tabsize=4]
[source,xml,indent=0,subs="verbatim,attributes"]
----
include::../maven/aot/pom.xml[tags=aot]
include::example$aot/pom.xml[tags=aot]
----
As the `BeanFactory` is fully prepared at build-time, conditions are also evaluated.
This has an important difference compared to what a regular Spring Boot application does at runtime.
For instance, if you want to opt-in or opt-out for certain features, you need to configure the environment used at build time to do so.
The `process-aot` goal shares a number of properties with the <<run,run goal>> for that reason.
The `process-aot` goal shares a number of properties with the xref:run.adoc[run goal] for that reason.
[[aot.processing-applications.using-the-native-profile]]
=== Using the Native Profile
If you use `spring-boot-starter-parent` as the `parent` of your project, a `native` profile can be used to streamline the steps required to build a native image.
The `native` profile configures the following:
* Execution of `process-aot` when the Spring Boot Maven Plugin is applied on a project.
* Suitable settings so that <<build-image,build-image>> generates a native image.
* Sensible defaults for the {nbt-reference}[Native Build Tools Maven Plugin], in particular:
* Suitable settings so that xref:build-image.adoc[build-image] generates a native image.
* Sensible defaults for the {url-native-build-tools-docs-maven-plugin}[Native Build Tools Maven Plugin], in particular:
** Making sure the plugin uses the raw classpath, and not the main jar file as it does not understand our repackaged jar format.
** Validate that a suitable GraalVM version is available.
** Download third-party reachability metadata.
To benefit from the `native` profile, a module that represents an application should define two plugins, as shown in the following example:
[source,xml,indent=0,subs="verbatim,attributes",tabsize=4]
[source,xml,indent=0,subs="verbatim,attributes"]
----
include::../maven/aot-native/pom.xml[tags=aot-native]
include::example$aot-native/pom.xml[tags=aot-native]
----
A single project can trigger the generation of a native image on the command-line using either {spring-boot-reference}/#native-image.developing-your-first-application.buildpacks.maven[Cloud Native Buildpacks] or {spring-boot-reference}/#native-image.developing-your-first-application.native-build-tools.maven[Native Image Build Tools].
A single project can trigger the generation of a native image on the command-line using either xref:reference:native-image/developing-your-first-application.adoc#native-image.developing-your-first-application.buildpacks.maven[Cloud Native Buildpacks] or xref:reference:native-image/developing-your-first-application.adoc#native-image.developing-your-first-application.native-build-tools.maven[Native Image Build Tools].
To use the `native` profile with a multi-modules project, you can create a customization of the `native` profile so that it invokes your preferred technique.
To bind Cloud Native Buildpacks during the `package` phase, add the following to the root POM of your multi-modules project:
[source,xml,indent=0,subs="verbatim,attributes",tabsize=4]
[source,xml,indent=0,subs="verbatim,attributes"]
----
include::../maven/aot-native-profile-buildpacks/pom.xml[tags=profile]
include::example$aot-native-profile-buildpacks/pom.xml[tags=profile]
----
The example below does the same for Native Build Tools:
[source,xml,indent=0,subs="verbatim,attributes",tabsize=4]
[source,xml,indent=0,subs="verbatim,attributes"]
----
include::../maven/aot-native-profile-nbt/pom.xml[tags=profile]
include::example$aot-native-profile-nbt/pom.xml[tags=profile]
----
Once the above is in place, you can build your multi-modules project and generate a native image in the relevant sub-modules, as shown in the following example:
[indent=0]
[source,shell]
----
$ mvn package -Pnative
$ mvn package -Pnative
----
NOTE: A "relevant" sub-module is a module that represents a Spring Boot application.
Such module must define the Native Build Tools and Spring Boot plugins as described above.
include::partial$goals/process-aot.adoc[leveloffset=+1]
include::goals/process-aot.adoc[leveloffset=+1]
[[aot.processint-tests]]
== Processing Tests
The AOT engine can be applied to JUnit 5 tests that use Spring's Test Context Framework.
Suitable tests are processed by the AOT engine in order to generate `ApplicationContextInitialzer` code.
Suitable tests are processed by the AOT engine in order to generate `ApplicationContextInitializer` code.
To configure your application to use this feature, add an execution for the `process-test-aot` goal, as shown in the following example:
[source,xml,indent=0,subs="verbatim,attributes",tabsize=4]
[source,xml,indent=0,subs="verbatim,attributes"]
----
include::../maven/aot-test/pom.xml[tags=aot]
include::example$aot-test/pom.xml[tags=aot]
----
TIP: If you are using `spring-boot-starter-parent`, this execution is automatically configured if you enable the `nativeTest` profile.
As with application AOT processing, the `BeanFactory` is fully prepared at build-time.

[[build-image]]
= Packaging OCI Images
The plugin can create an https://github.com/opencontainers/image-spec[OCI image] from a jar or war file using https://buildpacks.io/[Cloud Native Buildpacks] (CNB).
Images can be built on the command-line using the `build-image` goal.
This makes sure that the package lifecycle has run before the image is created.
NOTE: For security reasons, images build and run as non-root users.
See the {buildpacks-reference}/reference/spec/platform-api/#users[CNB specification] for more details.
See the {url-buildpacks-docs}/reference/spec/platform-api/#users[CNB specification] for more details.
The easiest way to get started is to invoke `mvn spring-boot:build-image` on a project.
It is possible to automate the creation of an image whenever the `package` phase is invoked, as shown in the following example:
[source,xml,indent=0,subs="verbatim,attributes",tabsize=4]

----
NOTE: Use `build-image-no-fork` when binding the goal to the package lifecycle.
This goal is similar to `build-image` but does not fork the lifecycle to make sure `package` has run.
In the rest of this section, `build-image` is used to refer to either the `build-image` or `build-image-no-fork` goals.
TIP: While the buildpack runs from an <<packaging,executable archive>>, it is not necessary to execute the `repackage` goal first as the executable archive is created automatically if necessary.

While you may start your Spring Boot application very easily from your test (or test suite) itself, it may be desirable to handle that in the build itself.

=== Custom Classifier
By default, the `repackage` goal replaces the original artifact with the repackaged one.
That is a sane behavior for modules that represent an application but if your module is used as a dependency of another module, you need to provide a classifier for the repackaged one.
The reason for that is that application classes are packaged in `BOOT-INF/classes` so that the dependent module cannot load a repackaged jar's classes.

With that setup, you can also override individual dependencies by overriding a property in your own project.

[[using.import]]
== Using Spring Boot without the Parent POM
There may be reasons for you not to inherit from the `spring-boot-starter-parent` POM.
You may have your own corporate standard parent that you need to use or you may prefer to explicitly declare all your Maven configuration.
If you do not want to use the `spring-boot-starter-parent`, you can still keep the benefit of the dependency management (but not the plugin management) by using an `import` scoped dependency, as follows:
[source,xml,indent=0,subs="verbatim,attributes",tabsize=4]
[source,xml,indent=0,subs="verbatim,attributes"]

include::../maven/using/no-starter-parent-pom.xml[tags=no-starter-parent]
include::example$using/no-starter-parent-pom.xml[tags=no-starter-parent]
----
The preceding sample setup does not let you override individual dependencies by using properties, as explained above.
To achieve the same result, you need to add entries in the `dependencyManagement` section of your project **before** the `spring-boot-dependencies` entry.
For instance, to use a different version of the SLF4J library and the Spring Data release train, you could add the following elements to your `pom.xml`:
[source,xml,indent=0,subs="verbatim,attributes",tabsize=4]
[source,xml,indent=0,subs="verbatim,attributes"]
----
include::../maven/using/no-starter-parent-override-dependencies-pom.xml[tags=no-starter-parent-override-dependencies]
include::example$using/no-starter-parent-override-dependencies-pom.xml[tags=no-starter-parent-override-dependencies]
----
[[using.overriding-command-line]]
== Overriding settings on the command-line
The plugin offers a number of user properties, starting with `spring-boot`, to let you customize the configuration from the command-line.
For instance, you could tune the profiles to enable when running the application as follows:
[indent=0]
[source,shell]
----
$ mvn spring-boot:run -Dspring-boot.run.profiles=dev,local
$ mvn spring-boot:run -Dspring-boot.run.profiles=dev,local
----
If you want to both have a default while allowing it to be overridden on the command-line, you should use a combination of a user-provided project property and MOJO configuration.
[source,xml,indent=0,subs="verbatim,attributes",tabsize=4]
[source,xml,indent=0,subs="verbatim,attributes"]
----
include::../maven/using/default-and-override-pom.xml[tags=default-and-override]
include::example$using/default-and-override-pom.xml[tags=default-and-override]
----
The above makes sure that `local` and `dev` are enabled by default.
Now a dedicated property has been exposed, this can be overridden on the command-line as well:
[indent=0]
[source,shell]

$ mvn spring-boot:run -Dapp.profiles=test
$ mvn spring-boot:run -Dapp.profiles=test
