Research direction

Start by reproducing concurrent sam build commands on a Windows build host using two workspaces and a dotnetcore3.1 Lambda. Read the related issues #126 and #127 for the proposed direction; done means concurrent builds no longer fail while updating the Amazon.Lambda.Tools global tool.

Description:

Receiving error from sam build when building a dotnet core 3.1 lambda function on a CI build server that is running more than one agent.

Error: DotnetCliPackageBuilder:GlobalToolInstall - Error configuring the Amazon.Lambda.Tools .NET Core Global Tool: Dotnet CLI Failed: Tool 'amazon.lambda.tools' failed to update due to the following:

Failed to uninstall tool 'amazon.lambda.tools': Failed to retrieve tool configuration: The process cannot access the file 'C:\Users\CruiseControl\.dotnet\tools\.store\amazon.lambda.tools\4.3.0\amazon.lambda.tools\4.3.0\tools\netcoreapp2.1\any\DotnetToolSettings.xml' because it is being used by another process.

Steps to reproduce the issue:

  1. Create a SAM project that includes a lambda with the dotnetcore3.1 runtime
  2. Create two different workspaces with the same code on your machine
  3. run sam build concurrently until the file locking issue is encountered

Additional environment details (Ex: Windows, Mac, Amazon Linux etc) observed on a windows build host

This seems related to #126 and would likely be resolved by #127 as well. Is there any timeline for releasing that change?
