Hi,

We are getting this below exception when building the theme. We are usign 7.2 and building the plugins in proxy enviroinment. All the plugins are successfully build from liferay repository... but this below depedency has  this issue.

Tried all possible way but no luck.

1. Added proxy properties in gradle.properties

2. Added SSL certificates into java security lib

But no luck.... is there any way that i can download those files and added into gradle cache folder manually? 

Here is the build.gradle file:

buildscript {
    dependencies {
        classpath group: "com.liferay", name: "com.liferay.gradle.plugins.theme.builder", version: "2.0.7"
    }

    repositories {
        maven {
            url "http://repository-cdn.liferay.com/nexus/content/groups/public"
        }
    }
}
plugins {
  id "com.eriwen.gradle.js" version "2.14.1"
}
apply plugin: "com.liferay.portal.tools.theme.builder"
dependencies {
    parentThemes group: "com.liferay", name: "com.liferay.frontend.theme.styled", version: "4.0.2"
    parentThemes group: "com.liferay", name: "com.liferay.frontend.theme.unstyled", version: "4.0.1"

    portalCommonCSS group: "com.liferay", name: "com.liferay.frontend.css.common", version: "4.0.0"

    themeBuilder group: "com.liferay", name: "com.liferay.portal.tools.theme.builder", version: "1.1.7"
    
    cssBuilder group: "com.liferay", name: "com.liferay.css.builder", version: "3.0.0"
}
