3. If prompted, exclude the `spring-aspects` module (or after the import by closing or
deleting the project)
4. In the `spring-oxm` project, add the `jaxb` folder in
`build/generated-sources` to the build path (right click on them and select
`Build Path -> Use as Source Folder`)
5. To apply project specific settings run `./gradlew eclipseBuildship`
7. Code away
_When instructed to execute `./gradlew` from the command line, be sure to execute it within your locally cloned `spring-framework` working directory._
1. Ensure that Eclipse launches with JDK 8.
- For example, on Mac OS this can be configured in the `Info.plist` file located in the `Contents` folder of the installed Eclipse or STS application (e.g., the `Eclipse.app` file).
1. Install the [Kotlin Plugin for Eclipse](http://marketplace.eclipse.org/content/kotlin-plugin-eclipse) in Eclipse.
1. Install the [Eclipse Groovy Development Tools](https://github.com/groovy/groovy-eclipse/wiki) in Eclipse.
1. Switch to Groovy 2.5 (Preferences -> Groovy -> Compiler -> Switch to 2.5...) in Eclipse.
1. Change the _Forbidden reference (access rule)_ in Eclipse from Error to Warning
(Preferences -> Java -> Compiler -> Errors/Warnings -> Deprecated and restricted API -> Forbidden reference (access rule)).
1. Optionally install the [AspectJ Development Tools](https://www.eclipse.org/ajdt/downloads/) (_AJDT_) if you need to work with the `spring-aspects` project.
1. Optionally install the [TestNG plugin](https://testng.org/doc/eclipse.html) in Eclipse if you need to execute TestNG tests in the `spring-test` module.
1. Build `spring-oxm` from the command line with `./gradlew :spring-oxm:check`.
1. To apply project specific settings, run `./gradlew eclipseBuildship` from the command line.
1. Import into Eclipse (File -> Import -> Gradle -> Existing Gradle Project -> Navigate to the locally cloned `spring-framework` directory -> Select Finish).
- If you have not installed AJDT, exclude the `spring-aspects` project from the import, if prompted, or close it after the import.
- If you run into errors during the import, you may need to set the _Java home_ for Gradle Buildship to the location of your JDK 8 installation in Eclipse (Preferences -> Gradle -> Java home).
1. If you need to execute JAXB-related tests in the `spring-oxm` project and wish to have the generated sources available, add the `build/generated-sources/jaxb` folder to the build path (right click on the `jaxb` folder and select `Build Path -> Use as Source Folder`).
- If you do not see the `build` folder in the `spring-oxm` project, ensure that the "Gradle build folder" is not filtered out from the view. This setting is available under "Filters" in the configuration of the Package Explorer (available by clicking on the small downward facing arrow in the upper right corner of the Package Explorer).
1. Code away!
## Known Issues
1. `spring-core` and `spring-oxm` should be pre-compiled due to repackaged dependencies.
- See `*RepackJar` tasks in the build.
2. `spring-aspects` does not compile due to references to aspect types unknown to Eclipse.
- If you install [AJDT](https://www.eclipse.org/ajdt/downloads/) into Eclipse it should
work.
3. While JUnit tests pass from the command line with Gradle, some may fail when run from

- If you installed _AJDT_ into Eclipse it should work.
1. While JUnit tests pass from the command line with Gradle, some may fail when run from
the IDE.
- Resolving this is a work in progress.
- If attempting to run all JUnit tests from within the IDE, you will likely need to set
the following VM options to avoid out of memory errors:
