| # Contributing to Spring Boot | ||
|
|
||
| Spring Boot is released under the non-restrictive Apache 2.0 license. If you would like | ||
| to contribute something, or simply want to hack on the code this document should help | ||
| you get started. | ||
|
|
||
| ## Sign the Contributor License Agreement | ||
|
|
||
| Before we accept a non-trivial patch or pull request we will need you to sign the | ||
| [contributor's agreement](https://support.springsource.com/spring_committer_signup). | ||
| Signing the contributor's agreement does not grant anyone commit rights to the main repository, but it does mean that we | ||
| can accept your contributions, and you will get an author credit if we do. Active contributors might be asked to join | ||
| the core team, and given the ability to merge pull requests. | ||
|
|
||
| ## Code Conventions and Housekeeping | ||
|
|
||
| None of these is essential for a pull request, but they will all help. They can also be added after the original pull | ||
| request but before a merge. | ||
|
|
||
| * Use the Spring Framework code format conventions. Import `eclipse-code-formatter.xml` from the `eclipse` folder of the project | ||
| if you are using Eclipse. If using IntelliJ, copy `spring-intellij-code-style.xml` to `~/.IntelliJIdea*/config/codestyles` | ||
| and select spring-intellij-code-style from Settings -> Code Styles. | ||
| * Make sure all new .java files to have a simple Javadoc class comment with at least an @author tag identifying you, and | ||
| preferably at least a paragraph on what the class is for. | ||
| * Add the ASF license header comment to all new .java files (copy from existing files in the project) | ||
| * Add yourself as an @author to the .java files that you modify substantially (more than cosmetic changes). | ||
| * Add some Javadocs and, if you change the namespace, some XSD doc elements. | ||
| * A few unit tests would help a lot as well - someone has to do it. | ||
| * If no-one else is using your branch, please rebase it against the current master (or other target branch in the main project). | ||
|
|
||
| ## Working with the code | ||
| If you don't have an IDE preference we would recommend that you use | ||
| [Spring Tools Suite](http://www.springsource.com/developer/sts) or | ||
| [Eclipse](http://eclipse.org) when working with the code. We use the | ||
| [m2eclipe](http://eclipse.org/m2e/) eclipse plugin for maven support. Other IDEs | ||
| and tools should also work without issue. | ||
|
|
||
| ### Building from source | ||
| To build the source you will need to install | ||
| [Apache Maven](http://maven.apache.org/run-maven/index.html) v3.0 or above. | ||
|
|
||
| #### Default build | ||
| The project can be built from the root directory using the standard maven command: | ||
|
|
||
| $ mvn clean install | ||
|
|
||
| > **NOTE:** You may need to increase the amount of memory available to Maven by setting | ||
| > a `MAVEN_OPTS` environment variable with the value `-Xmx512m -XX:MaxPermSize=128m` | ||
| If you are rebuilding often, you might also want to skip the tests until you are ready | ||
| to submit a pull request: | ||
|
|
||
| $ mvn clean install -DskipTests | ||
|
|
||
| #### Full Build | ||
| Multi-module Maven builds cannot directly include maven plugins that are part of the | ||
| reactor unless they have previously been built. Unfortunately this restriction causes | ||
| some compilations for Spring Boot as we include a maven plugin and use it within the | ||
| samples. The standard build works around this restriction by launching the samples via | ||
| the `maven-invoker-plugin` so that they are not part of the reactor. This works fine | ||
| most of the time, however, sometimes it useful to run a build that includes all modules | ||
| (for example when using `maven-versions-plugin`. We use the full build on our CI servers | ||
| and during the release process. | ||
|
|
||
| Running a full build is a two phase process. | ||
|
|
||
| 1) Prepare the build | ||
|
|
||
| Preparing the build will compile and install the `spring-boot-maven-plugin` so that it | ||
| can be referenced during the full build. It also generates a `settings.xml` file that | ||
| enables a `snapshot`, `milestone` or `release` profiles based on the version being | ||
| build. To prepare the build, from the root directory use: | ||
|
|
||
| $ mvn -P snapshot,prepare install | ||
|
|
||
| > **NOTE:** You may notice that preparing the build also changes the | ||
| > `spring-boot-starter-parent` POM. This is required for our release process to work | ||
| > correctly. | ||
| 2) Run the full build | ||
|
|
||
| Once the build has been prepared, you can run a full build using the following commands: | ||
|
|
||
| $ cd spring-boot-full-build | ||
| $ mvn -s ../settings.xml -P full clean install | ||
|
|
||
| We generate more artifacts when running the full build (such as Javadoc jars), so you | ||
| may find the process a little slower than the standard build. | ||
|
|
||
| ### Importing into eclipse with m2eclipse | ||
| We recommend the [m2eclipe](http://eclipse.org/m2e/) eclipse plugin when working with | ||
| eclipse. If you don't already have m2eclipse installed it is available from the "eclipse | ||
| marketplace". | ||
|
|
||
| Spring Boot includes project specific source formatting settings, in order to have these | ||
| work with m2eclipse, we provide an additional eclipse plugin that you can install: | ||
|
|
||
| * Select `Install new software` from the `help` menu | ||
| * Click `Add...` to add a new repository | ||
| * Click the `Archive...` button | ||
| * Select `org.eclipse.m2e.maveneclipse.site-0.0.1-SNAPSHOT-site.zip` | ||
| from the `eclipse` folder in this checkout | ||
| * Install "Maven Integration for the maven-eclipse-plugin" | ||
|
|
||
| _NOTE: This plugin is optional. Projects can be imported without the plugin, your code | ||
| changes just won't be automatically formatted._ | ||
|
|
||
| With the requisite eclipse plugins installed you can select | ||
| `import existing maven projects` from the `file` menu to import the code. You will | ||
| need to import the root `spring-boot` pom and the `spring-boot-samples` pom separately. | ||
|
|
||
| ### Importing into eclipse without m2eclipse | ||
| If you prefer not to use m2eclipse you can generate eclipse project meta-data using the | ||
| following command: | ||
|
|
||
| $ mvn eclipse:eclipse | ||
|
|
||
| The generated eclipse projects can be imported by selecting `import existing projects` | ||
| from the `file` menu. | ||
|
|
||
| ### Importing into other IDEs | ||
| Maven is well supported by most Java IDEs. Refer to you vendor documentation. | ||
|
|
||
| ### Integration tests | ||
| The sample application are used as integration tests during the build (when you | ||
| `mvn install`). Due to the fact that they make use of the `spring-boot-maven-plugin` | ||
| they cannot be called directly, and so instead are launched via the | ||
| `maven-invoker-plugin`. If you encounter build failures running the integration tests, | ||
| check the `build.log` file in the appropriate sample directory. | ||
