为什么gradle依赖项的xml配置都带有“ Gradle__”前缀？ Intellij IDEA 13

Question

Java Spring project with Gradle 1.9 and vertx. Local gradle distribution. Some lines of build.gradle

apply plugin 'java'
apply plugin 'groovy'
apply plugin 'idea'

buildscript {
    repositories {
        jcenter()
    }
}

repositories {
mavenCentral()
}

dependencies {
            ...
            compile 'org.springframework:spring-context-support:3.2.5.RELEASE'
            compile 'org.springframework:spring-aop:3.2.5.RELEASE'
            compile 'org.springframework:spring-aspects:3.2.5.RELEASE'
            ...
}

I have an existing gradle project downloaded from git with xml configs in .idea/libraries folder named spring-aop_3_2_5_RELEASE.xml , for example, where we can find xml tag <library name="spring-aop-3.2.5.RELEASE">...</library> . After I had imported this project new file Gradle__spring-aop_3_2_5_RELEASE.xml appeared with only difference in name attribute of the library tag: Gradle: spring-aop-3.2.5.RELEASE . So i have duplicate xml configs for dependencies. I wonder why my gradle added that prefix.

The prefix is hardcoded, IDEA 13 needs a reimport of your old Gradle projects that were created in IDEA 12. It's not obvious, but there will be a notification about it in the next update.

In the Gradle generated project you can exclude the library files from the version control, same for the .iml files that can be also ignored when using Maven. Other files can be still shared (like code style, run configurations, inspection profiles, etc). Check this document for details.
