-The following has been tested against IntelliJ IDEA 2016.2.2
-
-## Steps
-
-_Within your locally cloned spring-framework working directory:_
-
-1. Precompile `spring-oxm` with `./gradlew :spring-oxm:compileTestJava`
-2. Import into IntelliJ (File -> New -> Project from Existing Sources -> Navigate to directory -> Select build.gradle)
-3. When prompted exclude the `spring-aspects` module (or after the import via File-> Project Structure -> Modules)
-4. Code away
-
-## Known issues
-
-1. `spring-core` and `spring-oxm` should be pre-compiled due to repackaged dependencies.
-See `*RepackJar` tasks in the build and https://youtrack.jetbrains.com/issue/IDEA-160605).
-2. `spring-aspects` does not compile due to references to aspect types unknown to
-IntelliJ IDEA. See https://youtrack.jetbrains.com/issue/IDEA-64446 for details. In the meantime, the
-'spring-aspects' can be excluded from the project to avoid compilation errors.
-3. While JUnit tests pass from the command line with Gradle, some may fail when run from
-IntelliJ IDEA. Resolving this is a work in progress. If attempting to run all JUnit tests from within
-IntelliJ IDEA, you will likely need to set the following VM options to avoid out of memory errors:
-    -XX:MaxPermSize=2048m -Xmx2048m -XX:MaxHeapSize=2048m
-4. If you invoke "Rebuild Project" in the IDE, you'll have to generate some test
-resources of the `spring-oxm` module again (`./gradlew :spring-oxm:compileTestJava`)

-## Tips
-
-In any case, please do not check in your own generated .iml, .ipr, or .iws files.
-You'll notice these files are already intentionally in .gitignore. The same policy goes for eclipse metadata.
