I'm trying to install orientdb server on my Mac (High Sierra, Version 10.13.3) after downloading Java ( Version 8 Update 191) but I'm getting "Unsupported major.minor version 52.0" error. Can you help?
Doing ./server.sh or ./console.sh returns:
removing old pid file

I got the following error for the command ionic build android I don't have a clue what this error means. What should be done to rectify this error.I read that it happens if you dont have all the required platforms but I already installed almost all the versions of android along with latest build tools, support repositories and libraries.

Unsupported major.minor version 52.0 indicates that you need at least Java 8 to run the build, so try to update your JDK (Java class file number).

A detailed answer for my approach is highly appreciated.
You error suggest that you're using a lower JVM version than the one the application was build. Try upgrading your java version
I installed the google app engine sdk and plugin and every time I'm trying to save a java file my IDE (Eclipse Kepler) shows me an error window: "Java Virtual Machine Launcher - Could not find the main class com.google.appengine.tools.enhancer.Enhance. Program will exit".
In the console there is also a message:

Exception in thread "main"
It happens only in GAP and GWT projects...simple web or java projects are fine.
How can I fix it?
Thanks.

But I check my jar that the scala-lang.jar is in the lib folder, so it should be in classpath. But why here it can not find it?
Jeff Zhang
Please read question classpath-including-jar-within-a-jar.
Sorry, I make a stupid mistake. Actually I run scala in hadoop, and call "hadoop -jar" rather than "hadoop jar", such a stupid mistake.
