First, we need your build.gradle

Second, i can make a guess from what you have posted till now.

• Check your build.gradle for unused or missing projects in your project directory by checking dependencies area

as i can understand from "error listing versions of com.android.support:support-v4 using class org.gradle.api.internal.artifacts.repositories.resolver.MavenVersionLister$1. will attempt an alternate way to list versions. This behaviour has been deprecated and is scheduled to be removed in gradle 2.0" this.It may be related to repositories.

Check whether you have this or not in dependencies area. If something else is written there, remove it and add the correct one that i wrote below.

dependencies {
    ...
    repositories {
        mavenCentral()
        mavenLocal()
    }
...
}

• and my another guess is, there is something wrong in your support-v4 library implementation

check whether you have

    dependencies {
...
        compile 'com.android.support:support-v4:22.2.0'
...
    }

this or not. If not , add the line starts with compile that i wrote above. And If you have something like,

compile project(':support-v4')

remove that line.
