found solution. can choose 1 or 2

1. download gradle http://services.gradle.org/distributions/gradle-2.2.1-all.zip , paste in app\platforms\android\gradle , edit build.js in app\platforms\android\cordova\lib , change var distributionurl = 'distributionurl=http\://services.gradle.org/distributions/gradle-2.2.1-all.zip'; var distributionurl = 'distributionurl=../gradle-2.2.1-all.zip';
2. change var distributionurl = 'distributionurl=http\://services.gradle.org/distributions/gradle-2.2.1-all.zip'; var distributionurl = 'http://services.gradle.org/distributions/gradle-2.2.1-all.zip';
