问题
I am trying to experiment with Mule Runtime 4 & Anypoint Studio 7.1. I got the downloadable from -
https://mule-studio.s3.amazonaws.com/7.1.1-GA/AnypointStudio-for-win-64bit-7.1.1-201803182216.zip
while starting up AnypointStudio.exe, I keep getting the error message -
A JDK must be installed in order to run Anypoint Studio. Please install a JDK and try again.
But I do the required version of JDK installed in my machine, as per https://docs.mulesoft.com/anypoint-studio/v/7.1/faq-jdk-requirement
Here's the output from java -version
java version "1.8.0_161" Java(TM) SE Runtime Environment (build 1.8.0_161-b12) Java HotSpot(TM) 64-Bit Server VM (build 25.161-b12, mixed mode)
Can someone help identifying the issue?
回答1:
Make sure Java8 was installed in your system and Update AnypointStudio.ini file with below lines.
-vm
C:\Program Files\Java\jdk1.8.0_111\bin\javaw.exe

I think you have more than one version of java installed in your laptop, Please use the JDK 1.8 with the latest update and remove or uninstall all the older versions of it.
Please don't forgot to configure the JAVA HOME and Path environment variables in your laptop user account. enter image description here
and if still the problem exists, then uninstall all the versions of java and clear the temp folder of your laptop (or restart your laptop) and then try the fresh installation of jdk and jre 1.8 version, this kind of error comes when the jdk is not installed properly in your system.

Above solution works but there is another solution which is to add JAVA_HOME and PATH variables into Window's System variables. Make sure to put %JAVA_HOME%/bin as first variable of PATH variables' value.
By doing that you don't need to change any default configuration . Studio7 try to find out JDK path from first variable of "PATH" values under system variable instead of user variable under Environment variables .

not true, you can use as many JVM as you wish, just make system path to javaw.exe and server\jvm.dll
..;D:\jdk1.8\jre\bin;D:\jdk1.8\jre\bin\server;D:\jdk1.8\bin;...
and JAVA_HOME D:\jdk1.8 and fix anypointstudio.ini accordingly above described to your path of javaw.exe in my case D:\jdk1.8\jre\bin\javaw.exe
