[!] rjb cannot be installed and run on windows

[winezer0]

OS: windows 10 Lang: Chinese

BUG 1：

In a Chinese Env, the 'javah -version' invoked by the rjb installation cannot be matched with a normal RE, indicating an encoding error

javah -version
javah版本 "1.8.0_261"

BUG1 Cause:：rjb/ext/extconf.rb does not support Chinese encoding matching, please modify the code.

Temporary fix for BUG1：Change the language of the OS to english.

BUG 2:

After installing rjb with a temporary fix, every time you run the program:

[!] Partially dependent java plugins cannot be used normally

Please help me deal with this problem, thank you very much

@winezer0 Sorry for the late response. I'll fix it asap.

Hi @winezer0, I can't reproduce this issue, I wonder if you could attach or copy&paste the extconf.rb output.

[winezer0]

Thank you very much for your reply.

After My analysis, the problem is mainly caused by two reasons:

1 The jdk version cannot be obtained correctly

On windows environment, when I run 'javah-version', the output Chinese result or Or because the output is not captured, I recompiled the rjb code by modifying it

run raw extconf.rb on windows:

run gem install rjb:

run javah -version on windows:

my fix extconf.rb code:

# cversion = (javac -version =~ /\d+.\d+.\d+/ ) ? $& : nil javac_output = javac -version 2>&1 match = javac_output.match(/\d+.\d+.\d+/)
cversion = match ? match[0].to_s : nil
# hversion = (javah -version =~ /\d+.\d+.\d+/ ) ? $& : nil hversion = cversion puts "cversion:#{cversion}" puts "hversion:#{hversion}"

run my new extconf.rb on windows:

2. The rjb plug-in RuntimeError: can't create Java VM

Recompile and generate by configuring the environment

ruby setup.rb config ruby setup.rb setup ruby setup.rb install gem build rjb.gemspec gem install rjb-1.6.9-x64-mingw-ucrt.gem

However, there is still a JVM error

How should we deal with this issue? It seems to me that the issue of history has not been dealt with, is it impossible to solve it https://github.com/arton/rjb/issues/34

You can test a windows environment running rjb to see if it works
