SikuliX

Java 9: does not work with SikuliX 1.1.x (working on it --- see related bug)

Asked by simon smith

Hi,

I am trying to get Sikuli running under OSX 10.12.6 and having issues installing.
I got and installed the JDK from oracle (jdk-9_osx-x64_bin)
I then grabbed the 1.1.1 setup jar file (and also tried the nightly sikulixsetup-1.1.2-20170915.082449-36-forsetup version)

Checking java (java --verison) returns:
java 9
Java(TM) SE Runtime Environment (build 9+181)
Java HotSpot(TM) 64-Bit Server VM (build 9+181, mixed mode)

Double clicking on the jar file (after setting executable flag with chmod +x) does nothing.

Running from the terminal with:
java -jar ./sikulixsetup-1.1.1.jar

Returns the following error:
[error] RunTimeINIT: *** terminating: Java version must be 1.7 or later!

Any ideas as to what I'm doing wrong?
I had read that I should try with java 7, but that seems not to be accessable unless you are an Oracle customer. That aside, I assume it's best to use the latest and most secure version of Java anyway.

I've been using Sikuli under Windows for a while now, and it's been very useful, but I now need to transfer what I've done to OSX but this has kind of stopped me in my tracks!

Best Regards,
   Simon C. Smith.

SikuliX 1.1.x definitely does not work on Java 9 (and never will).

recommendation is, to install Java 8 on current OSX's.

If you have both on your machine (Java 8 and 9) you have to assure, that Java 8 is used at SikuliX runtime

... easiest option on macOS:
- in a Terminal session
- use the command /usr/libexec/java_home to get information about installed Java versions

/usr/libexec/java_home -V
lists the installed versions

/usr/libexec/java_home -v 1.8
switches the currently used version in this Terminal session

So in your case:
/usr/libexec/java_home should point to Java 9

/usr/libexec/java_home -V should list both Java 8 and 9

/usr/libexec/java_home -v 1.8 should switch to Java 8

On Windows with more than one Java installed, you can try with the Java settings in System setup or use The JAVA_HOME environment variable in a command line.
