Update my gradle dependencies in eclipse

I have a simple gradle project in my eclipse. I update the build.gradle to include a few apache http jars...

dependencies {
    compile group: 'commons-collections', name: 'commons-collections', version: '3.2'
    compile 'org.apache.httpcomponents:httpclient:4.2.3'
    compile "org.apache.httpcomponents:httpmime:4.2.3"
    testCompile group: 'junit', name: 'junit', version: '4.+'
}

However in my code, where I reference some Apache HTTP stuff I get:

The import org.apache.http cannot be resolved

Any tips on what I need to do to make Eclipse see the new dependencies in my build.gradle?

I tried doing a clean but that does not work. My gradle plugin is:

  Gradle IDE    3.3.0.201307040643-RELEASE  org.springsource.ide.eclipse.gradle.feature.feature.group   GoPivotal, Inc.

You have to select "Refresh Dependencies" in the "Gradle" context menu that appears when you right-click the project in the Package Explorer.

Looking at the Eclipse plugin docs I found some useful tasks that rebuilt my classpath and updated the required dependencies.

  • First try gradle cleanEclipse to clean the Eclipse configuration completely. If this doesn;t work you may try more specific tasks:
    • gradle cleanEclipseProject to remove the .project file
    • gradle cleanEclipseClasspath to empty the project's classpath
  • Finally gradle eclipse to rebuild the Eclipse configuration

You have to make sure that "Dependency Management" is enabled. To do so, right click on the project name, go to the "Gradle" sub-menu and click on "Enable Dependency Management". Once you do that, Gradle should load all the dependencies for you.

I tried all above options but was still getting error, in my case issue was I have not setup gradle installation directory in eclipse, following worked:

eclipse -> Window -> Preferences -> Gradle -> "Select Local Installation Directory"

Click on Browse button and provide path.

Even though question is answered, thought to share in case somebody else is facing similar issue.

Cheers !
