Error : Javatar cannot find JDK installed on your computer. #65

Closed quazi-irfan closed 8 years ago

quazi-irfan commented 8 years ago

At every startup I get the following error from Javatar "Javatar cannot find JDK installed on your computer".

But, I've updated the java installation location at Peference > Package Settings > Javatar > "Settings - Default",

From: "windows": ["C:\\Program Files\\Java", "C:\\Program Files (x86)\\Java"], To: "windows": ["C:\\Programs\\Java"],

On my system the java binaries are located at, C:\Programs\Java\jdk1.7.0_80\bin And my JAVA_HOME is set to, C:\Programs\Java

So, why can't Javatar find JDK on my system?

This the Sublime log after startup,

Please continue the discussion on #55 since I still need more information in order to solve this issue. And you can also find a relevant information and some diagnostic solutions there.

quazi-irfan commented 8 years ago

Since the other conversation is already cluttered, I am adding my information on this thread,

I am running on Windows 10 64bit, and I have only one java installed on my system. The path is set as follows,

C:\Users\iamcr>java -version
java version "1.7.0_80"
Java(TM) SE Runtime Environment (build 1.7.0_80-b15)
Java HotSpot(TM) 64-Bit Server VM (build 24.80-b11, mixed mode)

C:\Users\iamcr>where java
C:\Windows\System32\java.exe
C:\Programs\Java\jdk1.7.0_80\bin\java.exe

C:\Users\iamcr>where javac
C:\Programs\Java\jdk1.7.0_80\bin\javac.exe

I've also tried reinstalling Sublime Text 3. I am downloading Javatar zip from github for manual installation.

Do I have to have Package Control installed on Sublime?

Also, Preference > Package Settings > Javatar > Settings - Default shows me the following settings file,

Also, I didn't understand the following this you said,

When run the Java script which show java.home should returns the home directory of the executable that used to run the script

How do I check what java.home holds?

Also, I ran the following code snippet,

>>> import Javatar
>>> th = Javatar.threads.jdk_manager.JDKDetectorThread(
>>> th.is_jdk_path("C:\Programs\Java\jdk1.7.0_80\\bin")
True
>>> th.is_jdk_path("C:\Programs\Java")
False

I hope it helps narrowing down the problem...

spywhere commented 8 years ago

Hmm... feels like it java.home problems... could you try a v2.0.0-PreBeta.3? If that's worked then I think I know what the problem is...

Does it pin point the problem?

spywhere commented 8 years ago

Nope, it doesn't pin point the problem. But at least this should narrow down the problem a lot, thanks to your help. I'll report in both issue once I solve the problem.

spywhere commented 8 years ago

Ah.. After checking the code from the PreBeta.1 to PreBeta.5 this definitely be from a new JDK detection algorithm (introduced in PreBeta.3) since a new one required JAVA_HOME environment to be set in order to use. However, as a feature request in #53 this behaviour should be optional hence that's why Javatar cannot find the JDK. I'll adjust the JDK detection algorithm again and see if it works.

spywhere commented 8 years ago

Javatar v2.0.0-prebeta.6 is up. This release should fix JDK detection issue now. You should be able to use a new release within 6 hours :)
