sourceMap sources path

[tnbalu]

Hi, I have created a minified file and sourcemap file.

In the sourcemap file sources path is absolute path "ie" d:/abcd/sdsd/sdsd/employee.js but it shoule be employee.js

Can you guide me how to change the path in sources.

Issue:- While it is running in test environment it will look for d://.../../employee.js

1) Source map annotation prefix.

The generated minified source file is not containing the map file referance e.g. //@ sourceMappingURL=simple.js.map

Thanks!

Same issue here with version 1.12.0

It seem like closure compiler itself is not adding map file reference.

I see the same issue.. i digged down into the source and (without running it mind you) it looks like it uses the Google CompilerOptions object to configure this from JsMinifier.groovy:

• https://github.com/eriwen/gradle-js-plugin/blob/master/src/main/groovy/com/eriwen/gradle/js/JsMinifier.groovy#L22

If you can't wait for a fix to the plugin and just want to rewrite the sourcemap as a hack, you can do it in the doLast closure of the minifyJs task, something like: (my groovy-fu is rusty so feel free to make it better)

minifyJs {
    source = combineJs
    dest = file("${outputJsDir}/application.min.js")
    sourceMap = file("${outputJsDir}/application.min.map")
    closure {
        warningLevel = 'QUIET'
    }
    doLast {
        file("${outputJsDir}/application.min.js") << "\n//# sourceMappingURL=application.min.map"

        Map srcMap = new JsonSlurper().parseText( sourceMap.text )
        srcMap.sources = ["application.js"]
        sourceMap.withWriter("UTF-8") { it << new JsonBuilder(srcMap).toPrettyString() }
    }
}
tasks.minifyJs.dependsOn tasks.combineJs

Notes:

• I also had to add the last line to the minified js file pointing to the source map itself
• outputJsDir is my own thing I added where I output these files, and then throw them into the war file as normal

Thank you @djKianoosh that helped alot. For those that stumble upon this, fully qualify the class names:

    Map srcMap = new groovy.json.JsonSlurper().parseText( sourceMap.text )
    srcMap.sources = ["application.js"]
    sourceMap.withWriter("UTF-8") { it << new groovy.json.JsonBuilder(srcMap).toPrettyString() }

@dparish ah yes, I assumed import groovy.json.* at the top; same difference :)
