Can't open WinStartBuildServer


Already install Java 8 and setting the path, but i still can’t open build server.

Here my full java path

User Variable
JAVA_HOME C:\Program Files\Java\jdk1.8.0_202

System Variable:
C:\Program Files\Common Files\Oracle\Java\javapath;C:\Program Files\Java\jre1.8.


Here, my Java work correctly.

Here, WinStartFrontend work correctly.

Here, the path my Java setting.
JAVA HOME C:\Program Files\Java\jdk1.8.0_202
C:\Program Files\Java\jre1.8.0_202\bin;C:\Program Files\Common Files\Oracle\Java\javapath

Please help me find the solution. My college degree will be at risk if i can’t compile out the Application.


The path should point to jdk version not to jre version of JAVA


I have doing like you said, but it still same for me.


WinStartBuildServer runs in port 9990 so maybe your port is used by another app.


How to check what app that use that port?


Choose Start→All Programs→Accessories→System Tools→Resource Monitor

Then choose Network tab and see the ports in used by your computer


I didn’t see any app that take Port 9990, or it even didn’t exist.


Arg… i hope Appybuilder return the build server just for one day, no 1 minute for me to download my .apk


Try adding %JAVA_HOME%\bin in your path instead of c:\Program Files\Java… Also are you using 32bit or 64bit version of Java ?


Already adding %Java_Home%\bin or using %Java_Home%\bin;C:\Program Files\Java\jre1.8.0_202\bin
And still dosen’t work for the only BuildServer


Delete this , just add %Java_Home%\bin;


Still not work bro.
Btw, iam using Win 7 32 bit.


Set virtual memmory?



Yes, try to set virtual memory and see if it works.


Instead of changing path variables just go and change
in WinStartBuildServer file and replace with
path of your java installed
C:\Program Files\Java\jdk1.8.0_221\bin\java


If you configure your java path correctly you won’t have to do that, moreover other programs will work as they should as well



thanks is working for me
this my config win7 32bit
