java context from path cannot be modified

[maldag]

Description of the bug

Usage of dart run -vv build_runner build --delete-conflicting-outputs does not work, if provided "java" command on command line does not point to appropriate java version.

Due to native system requirements, the "java" command on console points to an older version of java.
The command in main.dart just uses the call to "java" which will be looked up on PATH.

Steps to reproduce

set Path environment variable to old java version.

Expected behavior

no exception like this:

Codegen Failed. Generator output: Exception in thread "main" java.lang.UnsupportedClassVersionError: org/openapitools/codegen/OpenAPIGenerator has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0

Additional context

Only relying on system path is not a robust implemention imho. It should consider using the Android SDK Version which `flutter doctor -v` correctly reports.
