java - Unable to resolve build fail exception for Gradle dependencies -

i've started working on spring security tutorials given on github. downloaded zip , when exported projects in eclipse , tried "build model" gave me exception message below.

could not resolve dependencies configuration ':runtime'. > not resolve com.google.appengine:appengine-tools-sdk:1.4.2. required by: :buildsrc:unspecified > not 'http://repo1.maven.org/maven2/com/google/appengine/appengine-tools-sdk/1.4.2/appengine-tools-sdk-1.4.2.pom'. received status code 407 server: proxy authorization required > not 'http://repository.springsource.com/maven/bundles/release/com/google/appengine/appengine-tools-sdk/1.4.2/appengine-tools-sdk-1.4.2.pom'. received status code 407 server: proxy authorization required > not 'http://repository.springsource.com/maven/bundles/external/com/google/appengine/appengine-tools-sdk/1.4.2/appengine-tools-sdk-1.4.2.pom'. received status code 407 server: proxy authorization required

with i've removed proxy settings i've provided in eclipse network connections , in case i'm not getting such proxy authorization error, couldn't resolve thing. if has thought cause ?

build.gradle

repositories { mavencentral() maven { name = 'springsource enterprise release' url = 'http://repository.springsource.com/maven/bundles/release' } maven { name = 'springsource enterprise external' url = 'http://repository.springsource.com/maven/bundles/external' } } dependencies { compile 'com.google.appengine:appengine-tools-sdk:1.4.2' }

you have

proxy authorization required

message in error string. need configure net connection proxy setrting. (e.g. in net explorer -> tool-> net option)

also may create sense check if mentioned versions of binaries on maven central http://mvnrepository.com/
