After a bit of digging I see that the closure compiler is using a
'native' program, "compiler", which is segfaulting. This results in
an empty string being passed into JSON.parse()
[INFO] SyntaxError: Unexpected end of JSON input
[INFO] at JSON.parse (<anonymous>)
[INFO] at ChildProcess.<anonymous> (/home/lmann/dev/guacamole-
client/guacamole/src/main/frontend/node_modules/closure-webpack-
plugin/src/closure-compiler-plugin.js:1007:34)
Looks like the closure compiler can use Java or Javascript instead of
native
const ClosurePlugin = require('closure-webpack-plugin'); module.exports = {
optimization: { minimizer: [ new ClosurePlugin({mode: 'STANDARD'}, { //
compiler flags here // // for debugging help, try these: // // formatting:
'PRETTY_PRINT' // debug: true, // renaming: false }) ] }
};
Options
*
platform - native, java or javascript. Controls which version to use
of closure-compiler.
By default the plugin will attempt to automatically choose the
fastest option available.
JAVASCRIPT does not require the JVM to be installed. Not all flags
are supported.
JAVA utilizes the jvm. Utilizes multiple threads for parsing and
results in faster compilation for large builds.
NATIVE only available on linux or MacOS. Faster compilation times
without requiring a JVM.
but I can't get either JAVA or JAVASCRIPT to work, for example:
// Minify using Google Closure Compiler
new ClosureWebpackPlugin({ mode: 'STANDARD'}, { platform: 'JAVA'}, {
Anyone have suggestions on how to force the use of a Java compiler??
