AndroidStudio构建项目异常:PKIX path bu

在给Android Studio 配置代理后，发现无法构建项目了，后来去掉代理也不行，一直报错：

解决方案

后来在google了一下，大部分都说是缺少什么证书导致的，发现这些都不行，真正原因在于项目中的gradle.properties配置文件中，原来我虽然在设置中去掉了代理，但是项目配置文件中没有去掉，只需把配置文件中的代理地址去掉即可:

#systemProp.https.proxyPort=8087
#systemProp.http.proxyHost=127.0.0.1
org.gradle.jvmargs=-Xmx4096M
org.gradle.daemon=true
android.useDeprecatedNdk=true
