Install kotlin problem on eclipse

The old version of eclipse+jdk1.8.0_101 was used before, and the message "No X509TrustManager implementation available" appeared when installing the kotlin plugin in the marketplace, reinstall the latest jdk1.8.0-162 and install the latest eclipse-jee-oxygen-2 -Win32 successfully installed the kotlin plugin after starting eclipse again. There is no need to delete the original jdk when installing jdk, it will be automatically installed in different subdirectories under the same directory. The original JDK directory is C:\Program Files\Java\jdk1.8.0_101, and now it is installed in C:\Program Files\ Java\jdk1.8.0_162, after installation, you need to change JAVA_HOME to the current C:\Program Files\Java\jdk1.8.0_162, other Path and CLASSPATH do not need to be changed
