use installed binary closure-compiler.jar - avoid extra download

[milahu]

situation
i already have downloaded a closure-compiler-v20200830.jar

problem
i have very limited bandwidth and disk space

solution
find the closure-compiler-v*.jar file in my $PATH and use it
and only if not found, fall back to download

implementation
probably as npm post-install script
to generate an env.js file with paths to java and closure-compiler
or to native binary files, closure-compiler.exe etc

any interest in this feature?

The problem is now the downloaded compiler has no guarantees to be compatible with the npm repository itself. Can't this just be accomplished by globally installing the npm package? npm install -g google-closure-compiler

I've thought quite a bit about this and its simply something we don't want to support. We want to keep the npm package in sync with the compiler versions.
