Gradle build of Android app in VSTS failing after running out of memory

Question

I have a gradle build in VSTS that is building an Android app and it's failing with the below error. Does the build machine really have to little memory or should I change some settings in gradle.properties , eg the org.gradle.jvmargs settings?

在文件gradle.properties指定参数org.gradle.jvmargs=-Xmx2048M -XX\\:MaxHeapSize\\=32g后，构建开始工作。
