Javatar cannot find JDK without `JAVA_HOME` set

[cinvoke]

Hi, I have tried setting linux to "/usr/lib/jvm" "/usr/lib/jvm/java-8-openjdk-amd64" "

Ive also changed the executable to :
// Executables that Javatar used "java_executables": { "build": "/usr/bin/javac", "run": "/usr/bin/java", "lint": "/usr/bin/javac", "version": "/usr/bin/java", "script": "/usr/bin/jrunscript" },

I'm not sure how else to get Javatar to see JDK. Should I be using a JAVA_HOME envvar?

actual locations: ll /usr/bin/java lrwxrwxrwx 1 root root 22 Aug 28 18:28 /usr/bin/java -> /etc/alternatives/java lrwxrwxrwx 1 root root 23 Oct 19 20:16 /usr/bin/javac -> /etc/alternatives/javac lrwxrwxrwx 1 root root 25 Oct 19 20:16 /usr/bin/javadoc -> /etc/alternatives/javadoc lrwxrwxrwx 1 root root 32 Oct 19 20:16 /usr/bin/javafxpackager -> /etc/alternatives/javafxpackager lrwxrwxrwx 1 root root 23 Oct 19 20:16 /usr/bin/javah -> /etc/alternatives/javah lrwxrwxrwx 1 root root 23 Oct 19 20:16 /usr/bin/javap -> /etc/alternatives/javap lrwxrwxrwx 1 root root 30 Oct 19 20:16 /usr/bin/javapackager -> /etc/alternatives/javapackager lrwxrwxrwx 1 root root 24 Oct 19 19:39 /usr/bin/javaws -> /etc/alternatives/javaws*

Thanks.

The executable settings must contain only file names. For the JDK installation path, you have to override the jdk_installation settings for Linux in the settings file to make the Javatar search into that directory.

JAVA_HOME detection is not implement yet right now. So, settings the JAVA_HOME variable does not help fix the issue.

[cinvoke]

That makes sense. However, when I point it to a directory that clearly has the jdk installation in it, it still says it cannot find JDK.
For example: My /usr/bin has java, javac, jrunscript

[spywhere]

Could you send me your settings configurations? And may be some logs from the Sublime Text's console.

[cinvoke]

Sure no prob. Sublime log: http://dpaste.com/2QRWQ4J

Sublime conf: http://dpaste.com/26CBRKF

[spywhere]

I didn't see your changes to jdk_installation. Are you sure you give me "your" settings not default settings

[cinvoke]

file: ~/.config/sublime-text-3/Packages/Javatar/Javatar.sublime-settings

i changed it back because i can reach all the java executables from /usr/bin:

~$ which java /usr/bin/java

settings: "jdk_installation": { "osx": ["/Library/Java/JavaVirtualMachines"], "windows": ["C:\Program Files\Java", "C:\Program Files (x86)\Java"], "linux": ["/usr/bin"] },

// Runtime required files
"java_runtime_files": {
    "runtime": ["rt.jar"]
},

// Executables that Javatar used
"java_executables": {
    "build": "javac",
    "run": "java",
    "lint": "javac",
    "version": "java",
    "script": "jrunscript"
},

[cinvoke]

I also have this, but wasnt sure it needed to be pointed to: http://dpaste.com/1KV65GV

[spywhere]

The JDK installation is correct from the file tree you give me. That is left with the Javatar cannot find that JDK. Could you try using the path /usr/lib/jvm/ instead of /usr/bin for the Linux key?

If this works, I think I have an idea of how this can happens.

[cinvoke]

Nope. same jdk not found.
console: http://dpaste.com/3FJ6VJH

/usr/lib/jvm > http://dpaste.com/0CJCW3F

[spywhere]

Try running these commands (one by one) in the Sublime Text's console...

import Javatar
th = Javatar.threads.jdk_manager.JDKDetectorThread()
th.is_jdk_path("<<Your JDK Path Here>>")

Try change the JDK path (in the command) to point to the bin directory of your JDK. This should returns True.

If it returns True, run the java -version in the terminal and send me your JDK path that works and also a version from the terminal.

[cinvoke]

interesting.. It sees everything in /usr/bin but my jdk lib is definitely in /usr/lib/jvm...

import Javatar th = Javatar.threads.jdk_manager.JDKDetectorThread() th.is_jdk_path("/usr/lib/jvm/java-8-openjdk-amd64/bin") False th.is_jdk_path("/usr/lib/jvm/java-8-openjdk-amd64/") False th.is_jdk_path("/usr/lib/jvm/") False th.is_jdk_path("/usr/lib/jvm") False th.is_jdk_path("/usr/bin") True

[spywhere]

Could you check the symlink of each executable file in the /usr/bin? I think it might point to different JDKs.

[cinvoke]

That was it: /usr/bin$ ll java lrwxrwxrwx 1 root root 22 Aug 28 18:28 java -> /etc/alternatives/java lrwxrwxrwx 1 root root 23 Oct 19 20:16 javac -> /etc/alternatives/javac lrwxrwxrwx 1 root root 25 Oct 19 20:16 javadoc -> /etc/alternatives/javadoc lrwxrwxrwx 1 root root 32 Oct 19 20:16 javafxpackager -> /etc/alternatives/javafxpackager lrwxrwxrwx 1 root root 23 Oct 19 20:16 javah -> /etc/alternatives/javah lrwxrwxrwx 1 root root 23 Oct 19 20:16 javap -> /etc/alternatives/javap lrwxrwxrwx 1 root root 30 Oct 19 20:16 javapackager -> /etc/alternatives/javapackager lrwxrwxrwx 1 root root 24 Oct 19 19:39 javaws -> /etc/alternatives/javaws*

Then i changed the linux key to point to /etc/alternatives. Still same error.

[spywhere]

At minimum, JDK should conform with the following rules...

• Consists of all executables (as in the settings) in one place (usually in the bin directory)
• When run the command with -version should display the version which must match with the pattern in the java_version_match key
• When run the Java script which show java.home should returns the home directory of the executable that used to run the script

If one of the rule is not match, the JDK will considered invalid.

[cinvoke]

looks like its java_version match. match is returning in jdk_manager.py but no groups nor lastIndex.

Regex: "(\d+.\d+.\d+)_?([0-9a-zA-Z]+)?" I tried running the regex from java_version_match key on the text i get when i run java -version in gskinner... this regex looks correct to me.

[cinvoke]

actually , that was from me hardcoding the java version trying to force the java_version_match key... i put that back ;)

so now i get: [Javatar] v2.0.0-prebeta.3 [Javatar] Snippet Class.javatar-snippet loaded [Javatar] Snippet Enumerator.javatar-snippet loaded [Javatar] Snippet Interface.javatar-snippet loaded [Javatar] No JDK found error: Javatar cannot find JDK installed on your computer.

[cinvoke]

I just purged all java and symlinks until no java jre nor jdk existed. then i installed open jre 7 and jdk 7. /usr/bin points the /etc/alternatives , where each java binary is linked to /usr/lib/jvm/java-7-openjdk-amd64/bin/

[spywhere]

The AttributeError: 'module' object has no attribute 'parse' error is just a network module error which is not a part of the JDK issue.

The RegEx will match both ? statement, this should give empty string instead of None since the group is valid.

[cinvoke]

im not sure if there is anything i can do from a config stance at this point. Ive tried everything i can find. All my paths are correct now i believe. I only have one version of Java installed. Have you seen many issues with openjdk7?

[spywhere]

No, I don't see many (reported) issues with OpenJDK. Most of the issue about JDK is just misconfigure the JDK paths.

I still don't have any clue of how it's happen if the JDK is valid. So, the only cause that might have is a detection sequence which lead to the following questions.

1. Could you send me the following things?
   • Path to each installed JDK (make sure the executable files is all exists)
   • Version informations from running the java -version command on each JDK
2. Could you send me the full console log when Sublime Text starts?
3. Could you try running Javatar with a fresh, new, Sublime Text with only Package Control and Javatar?

[spywhere]

After investigated with a help on #65 This issue should be solved in a next version. I'll update this issue and close it once I release a new version.

[spywhere]

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 :)

[quazi-irfan]

The error is gone, and it looks like Javatar is detecting JDK now. I've installed Java 8 on my system.
