Sikuli: Java not found error

Question

While installing Sikuli, I get the following error:

C:\Users\adb\Downloads>C:\Users\adb\Downloads\runSetup.cmd
'Files' is not recognized as an internal or external command,
operable program or batch file.
+++ Java not found in standard places C:\Program Files or C:\Program Files (x86)
+++ JAVA_HOME not specified
+++ ended with some errors

This occurs when I run the runSetup.cmd file.

I have installed both 32 and 64 bit versions of java and no other application seems to have a problem finding it (Like Minecraft and all Firefox application).

However, here are the locations of my Java installations:

C:\Program Files\Java\jre1.8.0_25

C:\Program Files (x86)\Java\jre1.8.0_25

Answer 1

You need to add JAVA_HOME as a system variable, and reference this on the Path.

• In windows, go to computer > Computer properties > advanced system properties > Advanced > Environment variables .
• Click on New under 'System Variables'.
• Give the variable name as JAVA_HOME and value as path/to/java .

• (For the path/to/java use the path to the Javascript Runtime Environment folder eg C:\\Program Files\\Java\\jre1.8.0_25\\ and not C:\\Program Files\\Java\\jre1.8.0_25\\bin )

• Edit the variable PATH and add %JAVA_HOME%/bin at the end. Close and start your cmd again.

• Note that on some systems, there can be a maximum number of allowed characters in the path, so you may have to remove some entries from the path if you've exceeded the maximum. Do this with caution, and make a backup first (usually MS SQL Server entries are safe to delete)

Answer 2

This problem is because Oracle has released a new version of Java. And the Sikuli install is looking for the 2 previes versions. (Current path for me is: C:\\Program Files (x86)\\Java\\jre1.8.0_40) I had the same problem with installing Sikuli on my new computer.

What I did is I modified the installation file, so that I can use it to install Sikuli on every new computer in my company. And to make sikuli recognize the latest Java version.

After modifing the "runSetup.cmd" you also need an adjusted "runIDE.cmd" for the IDE to recognize the latest Java version.

This is the adjusted code/file:

runSetup.cmd

@echo off
SETLOCAL

set SIKULIX_HOME=%~dp0
set PARMS=-Xms64M -Xmx512M -Dfile.encoding=UTF-8

if not defined JAVA_HOME goto CHECKJAVA
IF EXIST "%JAVA_HOME%\bin\java.exe" goto JAVA_OK
echo +++ JAVA_HOME specified but not useable %JAVA_HOME%

If you for example 'right-click' on the file "runSetup.cmd" and choose 'Edit' you get to see the code. If you replace the 'original' code with my adjusted code it will be able to install using the latest Java version.

Answer 3

For better compatibility, can try to download Java 7 32bit version, and set Java 7 installed path to Java Home environment variable. (if setup fail auto detection ).
