@kuwas thank you, i thought i was the only one experiencing this, couldn't find any record of this behavior online.

Please let me know if you find a solution, i'll do the same.

For me also sometimes it takes more than 1hr it ill crashes at 92%

Got this issue some days ago with the v1.5.0. (app crash at 10%)
It cames from a directory containing a "." used in an import. In my case it was a typo, i created a directory component.ts..
Fix that and your app will build normally, maybe with a jsheap error but that's a totally different issue :).

@PillowPillow thank you so much for your answer.

I have many directories containing dots in them such as event-snooze.component.
It's a convention i was exposed to a while ago.

Are you saying this i what's causing the problem?
Anyone from the Angular team that can confirm?

[PillowPillow]

I'm not saying that's not a bug of the new version, this should be fixed asap but yes it seems that using dot in directory break the current build process. You can try easily by creating a new project with a "dot directory". I had to implement one by one all my modules & components to found this issue ^^'.

[eyalhakim]

@PillowPillow i just tested it and it works.
Created a new project. Added a "dot directory", imported the component inside it, build works.

Any idea why that could be?

[PillowPillow]

Erf, your issue is surely related but it seems that directories with dots works if the part after the dot isn't an extension.
I created a repo sample with my issue : repo, it crashes at 10% like yours.

[praveenbm9321]

@PillowPillow but for me it takes more than 1 hr to build or it will stops at 92% , is there any solution for that, In V1.4.1 it was taking max of 5 to 10 min

[eyalhakim]

@PillowPillow i cannot thank you enough!
Found two rouge folders that ended with .ts and once renaming them project builds again!

You are a life saver!

[eyalhakim]

@praveenbm9321 for me the optimization at 92% takes 5 minutes now but before it used to be seconds. Probably depends on the machine and project size but i can tell that something changed there for the worse.
Maybe you should open an issue on that?

[praveenbm9321]

@eyalhakim For me also optimization at 92% takse 2 to 3 minutes only but it stucks at 92% and sometime it completes or stops there itself.But before it use complete build withing 5 to 10 min

[eyalhakim]

@praveenbm9321 try running it with --build-optimizer=false

It doesnt actually have to be a directory inside the project with a period name. In my case the project root directory itself had periods in its name app.angular.cli.ts, so that broke the build too. Renaming the entire project seems to work.

Regardless, period names are perfectly valid directories and should build. This is definitely something that should be fixed.
