Add publicpath: "http://localhost:8080/" in the arguments… now it works

extendWebpack(cfg) {
cfg.plugins.push(
new BundleTracker({
filename: “webpack-stats.json”,
publicPath: “http://localhost:8080/”
})
),
cfg.module.rules.push({
enforce: “pre”,
test: /.(js|vue)$/,
loader: “eslint-loader”,
exclude: /node_modules/,
options: {
formatter: require(“eslint”).CLIEngine.getFormatter(“stylish”)
}
});
}
