How to configure AWS SAM on Eclipse and Window 10

Question

I am using STS 4 (https://spring.io/tools) and added Eclipse AWS toolkit (https://marketplace.eclipse.org/content/aws-toolkit-eclipse) .

After restart STS we can see everything is good.

Now i have installed AWS SAM CLI local

And configured path where we have sam.exe

I have Java 8 and Python 2.7 and 3.6 and docker installed in my local.

Now created AWS Java serverless project maven install and try to run sam local

Update :

When i am try to run SAM-CLI its working and returning response.

I am wonder if anyone solved that issue ?

Answer 1

Had the same issue.

First you should open the command line and run where sam If you find that the path contains any spaces, for example, if it has 'Program Files' in its path then uninstall samcli and reinstall it. Make sure that its path does not contain any spaces, for example: C:\Amazon\SAMCLI. And when you're done installing samcli rerun the previous code in cmd and copy the path and paste in eclipse.

Secondly, you should follow Dimman's advice by creating a config file. You can do so by using awscli by running aws configuration

This will create the file automatically. Save and restart and everything should be fine.

Good luck.

Answer 2

Had the same issue, made the following changes and was able to continue...

In your section "And run configuration", in the image. Make sure that you have expanded the "Advanced" section and added the needed info,

• AWS Configuration

• SAM Local Configuration (this should be setup).

Also try adding doing the following. In your folder C:\Users\YOUR_USER.aws You should see two files, credentials, and config. I did not have the file config so I created it and added the following:

[default]
region=YOUR_REGION

I also added the following line under the [username] in the credentials file:

region=YOUR_REGION

I saved and restarted everything and got it to work. Now I have some other issues. But they are specific to JSON parsing.
