Repro steps

• Set apps[0].outDir as "../dist" on .angular-cli.json
• run ng b

Observed behavior

Only a error message: An asset cannot be written to a location outside the project.

Desired behavior

Build the project without problem.

Mention any other details that might be useful (optional)

We have tried to add allowOutsideDir to ours assets configuration on cli config, but doesn't work. Is this the expected behaviour? I don't found related information about it in de64b86 or #8122 :(

Same problem here.
I can't believe a major functionality of the CLI, "ng b", doesn't work after an update...
Downgrade to 1.5.3...

@hansl can you have a look please?

[p3root]

@hansl @filipesilva @rbluethl: This issue is occuring when the outdir in .angular-cli.json is outside the angular folder. (eg. "outDir": "../../bin/Debug/www")

@hansl @filipesilva : Same issue here. Please fix the issue.

".angular-cli.json" Config
...
"apps": [
{
"root": "src",
"outDir": "../web/src/main/resources/static",
"assets": [
...

On Build
>ng build
An asset cannot be written to a location outside the project.

Same problem, I'm using the outDir param to build outside my angular root folder.

// Prevent asset configurations from writing outside of the output path, except if the user
// specify a configuration flag.
// Also prevent writing outside the project path. That is not overridable.
const fullOutputPath = path.resolve(buildOptions.outputPath, asset.output);
if (!fullOutputPath.startsWith(projectRoot)) {
    const message = 'An asset cannot be written to a location outside the project.';
    throw new SilentError(message);
}

What flag is told about?

[guilhermejcgois]

@gvart I think that the flag is allowOutsideOutDir in the last section.
