原因：gradle在編譯過程中棧內存溢出
解決方案：在build.gradle配置文件中增加
dexOptions {
javaMaxHeapSize "2g"
}
//2g表示內存大小，32位的jdk最大好像不能超過3g，超過最大允許內存大小時會報下面這個錯誤
Successfully started process ‘command ‘/g3an/ci/jdk1.7.0_79/bin/java‘‘ Invalid maximum heap size: -Xmx4g The specified size exceeds the maximum representable size. Error: Could not create the Java Virtual Machine. Error: A fatal exception has occurred. Program will exit.

原因：JVM虛擬機的內存空間太小
解決方案：在用戶目錄下的gradle.properties文件中指定gradle編譯時使用的jvm空間大小
文件路徑：/home/[user]/.gradle/wrapper/gradle.properties
在文件中增加：org.gradle.jvmargs=-Xmx2048m
