Error occurred during initialization of VM

坑！坑！坑！

首先，先粘贴下使用 gradlew 生成jar包报的错。

Error occurred during initialization of VM

Could not reserve enough space for 2097152KB object heap

Java HotSpot(TM) Client VM warning: ignoring option MaxPermSize=512m; support was removed in 8.0

第二行：去 gradle.properties  改为如下行代码

org.gradle.jvmargs=-Xmx512m       

之前设置 4096m然后改 位512m就可以了

第三行：我理解的意思是 java1.8可以忽略 MaxPermSize=512m （好像可以忽略）。
