Not possible start Spring Cloud Data Flow in Windows about spring-cloud-deployer-local HOT 9 CLOSED

I think simply caused because we check if physical file is there and use java as file name. However in windows its java.exe thought in command line you can just type java.

File javaExecutable = new File(javaHome, "bin/" + javaExecutablePath);
Assert.isTrue(javaExecutable.canExecute(), "Java executable discovered via 'java.home' system property '"
		+ javaHome + "' is not executable or does not exist.");

This seems like a similar problem described in #49. @manueljordan: Please override SPRING_CLOUD_DEPLOYER_LOCAL_JAVA_CMD property as described here and share your findings.

@sabbyanandan There is no workaround other than creating java file on windows as that Assert happens on a class construction level.

Thanks by the explanation @jvalkeal

Hi @sabbyanandan I did the following combinations in the same console:

For JDK

• SET SPRING_CLOUD_DEPLOYER_LOCAL_JAVA_CMD=C:\whiteroom\java\jdk1.8.0_131\bin
• SET SPRING_CLOUD_DEPLOYER_LOCAL_JAVA_CMD=C:\whiteroom\java\jdk1.8.0_131\bin;%PATH%

For JRE

• SET SPRING_CLOUD_DEPLOYER_LOCAL_JAVA_CMD=C:\whiteroom\java\jre1.8.0_131\bin
• SET SPRING_CLOUD_DEPLOYER_LOCAL_JAVA_CMD=C:\whiteroom\java\jre1.8.0_131\bin;%PATH%

For any of these possible 4 options, I got the same issue yet.

Not sure if I am doing something wrong

from spring-cloud-deployer-local.

I see, anyway I will do my experiments through Mac.

Thanks by the support.

I tried copying java.exe to java. Same error. Let me know if you intended for something to be done.

c:\Home>echo %JAVA_HOME%
"C:\Program Files\Java\jre1.8.0_131"

c:\Users\lgoolsby\Documents\Java\Projects>cd %JAVA_HOME%

C:\Program Files\Java\jre1.8.0_131>cd bin

C:\Program Files\Java\jre1.8.0_131\bin>copy java.exe java
        1 file(s) copied.

@lanegoolsby either java points to wrong jvm or forward slash causes issues.

new File(javaHome, "bin/" + javaExecutablePath)

What windows version you have?

from spring-cloud-deployer-local.

Win2012 server. It appears your hypothesis that the slash is the problem appears correct. I ran the JAR from a PoSh shell instead of CMD and it appears to be working.

from spring-cloud-deployer-local.

Oh, ok thanks for pointing it out. Assuming that's the case I need to fix the PR not to use slash on win.
