描述

bug

🐛 Bug Report:

Describe the bug

The content of the environment variable JAVA_OPTS is evaluated. In case it contains a | character, then the next part of it is interpreted as a new command.

I'm in a corporate network that is secured by a proxy. My JAVA_OPTS environment variable defines the settings so that Java can use the proxy:

$ env | grep JAVA_OPTS
JAVA_OPTS=-Dhttp.proxyHost=localhost -Dhttp.proxyPort=9000 -Dhttps.proxyHost=localhost -Dhttps.proxyPort=9000 -Dhttp.nonProxyHosts=127.*|localhost|*.local
$

The http.nonProxyHosts contains the | character as described by Java. The normal Java applications accept this environment variable correctly.

Steps to Reproduce

Steps to reproduce the behavior:

  1. Go to en empty directory.
  2. Install the cli:
    npm install -g @openapitools/openapi-generator-cli
  3. Call the generator without a | in the JAVA_OPTS:
    JAVA_OPTS="-Dhttp.nonProxyHosts=localhost" openapi-generator-cli help
  4. Call the generator with a | in the JAVA_OPTS:
    JAVA_OPTS="-Dhttp.nonProxyHosts=127.*|localhost" openapi-generator-cli help
Actuall response

The command from point 4. returns the error message:

Error: 'localhost' is not recognized as an internal or external command,
operable program or batch file.

Node.js v22.22.3
Expected behavior

The command from point 3. returns a correct help response. The command from point 4. should return the same response.

N/A

Operation System (please complete the following information):
  • OS: Windows with a git-bash
  • Version 11
Package System (please complete the following information):
  • Version: Node.js 22
Additional context

I expect that the problem is that the java command with paramaters is evaluated too much. There are somewhere quotes missing. During the evaluation, the | character is then interpreted by the shell as a command pipe end the next part is expected to be a command (which it isn't). Additional quotes inside my environment variable is not needed. The normal shell doesn't automatically evaluate the content as a pipe. The following command (without additional quotes) returns the correct output:

$ echo $JAVA_OPTS
-Dhttp.proxyHost=localhost -Dhttp.proxyPort=9000 -Dhttps.proxyHost=localhost -Dhttps.proxyPort=9000 -Dhttp.nonProxyHosts=127.*|localhost|*.local
$
