jenkins无法访问https解决方法

mac上，jenkins在构建时需要访问https的url，报错如下：

Gradle 5.0\. Set the '[rootProject.name](rootProject.name)' or adjust the 'include' statement (see [https://docs.gradle.org/4.4/dsl/org.gradle.api.initialization.Settings.html#org.gradle.api.initialization.Settings:include(java.lang.String](https://docs.gradle.org/4.4/dsl/org.gradle.api.initialization.Settings.html#org.gradle.api.initialization.Settings:include(java.lang.String)[]) for more details).

FAILURE: Build failed with an exception.

* What went wrong:

A problem occurred configuring root project 'saas android package'.

* Try:

解决方法：

1. 在Mac中是Keychain，打开之后找到StartCom的证书，然后右键导出成一个.cer文件，命名为startcom.cer。

2. keytool -import -alias startcom -keystore /Library/Java/JavaVirtualMachines/jdk1.8.0_91.jdk/Contents/Home/jre/lib/security/cacerts -file startcom.cer

3. keytool -list -keystore /Library/Java/JavaVirtualMachines/jdk1.8.0_91.jdk/Contents/Home/jre/lib/security/cacerts | less

4. 启动jenkins
   java -Djavax.net.ssl.trustStore="/Library/Java/JavaVirtualMachines/jdk1.8.0_91.jdk/Contents/Home/jre/lib/security/cacerts" -Djavax.net.ssl.keyStorePassword=changeit -jar /usr/local/Cellar/jenkins/2.124/libexec/jenkins.war --httpPort=8080

5. 至此，问题解决
