longReporter and fullReporter are not using custom typescript

[a8775]

I can set custom typescript compiler eg:

var tsProject = ts.createProject('tsconfig.json', {
    typescript: require('requireg')('typescript')
});

When using defaultReporter and nullReporter compilation is working fine.

When you switch to the longReporter or fullReporter the custom typescript compiler is not used any more.

Full example of gulpfile:

var gulp = require('gulp');
var ts = require('gulp-typescript');
var sourcemaps = require('gulp-sourcemaps');


var tsProject = ts.createProject('tsconfig.json', {
    typescript: require('requireg')('typescript')
});


gulp.task('default', ['build']);

gulp.task('build', function () {
    var tsResult = tsProject.src()
        .pipe(tsProject(
            ts.reporter.longReporter()
        ));
    return tsResult;
});

The problem is how the typescript is required in longReporter and fullReporter, eg.:

function longReporter() {
    var typescript = require('typescript');
    ....
