Hello, can you run ./gradlew appengineRun and show us the error message(s) in the console when you retry this action again?

[damithc]

@rmit-s3649928-hongyi-zheng on a related note, can you point us to any online info about the course/module that requires you to work on TEAMMATES as an assignment? Thanks.

The course name is Software Engineering: Process and Tools and here is the link to the course info:

@rmit-s3649928-hongyi-zheng Might be due to the date/time language. Can you switch to English and see if it works? You can refer to this link for a rough reference.

[rmit-s3649928-hongyi-zheng]

@tanhengyeow I tried to switch but it seems that the version of Win 10 I use only support one language and I can't change it. Trying to find a way to do so at the moment.

[xpdavid]

Are you using Java8?

[rmit-s3649928-hongyi-zheng]

@xpdavid
Yes

[LiHaoTan]

I didn't look at the problem but assuming the problem is language related you can run it with the VM options:
-Duser.language=en -D.user.country=US

[rmit-s3649928-hongyi-zheng]

@LiHaoTan
Still generates the same error.

thanks @rmit-s3649928-hongyi-zheng

@rmit-s3649928-hongyi-zheng can I check what locale are you using? In particular, the output of Locale.getDefault(Locale.Category.FORMAT).

[rmit-s3649928-hongyi-zheng]

@LiHaoTan
It's located at D:\my_project and was at C:\Users:\my_project before I reinstalled it.

[LiHaoTan]

Sorry, I'm not catching what you are saying. Are you saying it's working now?

I was asking for your locale (i.e. your region and language settings). In particular, I want to know what is the output of Locale.getDefault(Locale.Category.FORMAT).

[rmit-s3649928-hongyi-zheng]

@LiHaoTan

Sorry I misunderstood what you said.I'm not sure how to get the output,but the system's region is Australia and the language is Chinese.

[LiHaoTan]

@rmit-s3649928-hongyi-zheng You just need print out the output and you can do that anywhere.

For example, go to TimeHelper.java:508 and replace with this:

Assumption.fail("Date in String is in wrong format." + Locale.getDefault(Locale.Category.FORMAT));

Then try adding an instructor again and your stack trace should print out the relevant locale.

设置 -> 时间和语言 -> 其他日期、时间和区域设置 -> 更改日期、时间或数字格式 -> 格式 -> 英语（新加坡）

@rmit-s3649928-hongyi-zheng There's a very high chance that this works for you :)

[rmit-s3649928-hongyi-zheng]

@dalessr

Thx a lot,that works 👍 .Looks like the exception is caused by language setting.Adding instructor is working fine now.Thx for all the help!
