How to specify one frameworks: net6.0, net8.0 ?

Hello, I am learning the SBOM and I am trying to generate SBOM file by this tool, but when I 'docker build . -t ms_sbom_tool' the following error occurs:

target framework. The current project targets multiple frameworks, you must specify one of the following frameworks in order to publish: net6.0, net8.0 [/app/src/Microsoft.Sbom.Tool/Microsoft.Sbom.Tool.csproj]
The command '/bin/sh -c dotnet publish -r $RUNTIME --self-contained true -p:DebugType=None -p:DebugSymbols=false -p:PublishSingleFile=true -p:IncludeAllContentForSelfExtract=true -o output' returned a non-zero code: 1

How can I specify a framework? BTW: I followed: Building SBOM tool as docker image.

Looks like our Dockerfile needs to be updated thank you for pointing this out, in the meantime you could try changing this line and building again:

https://github.com/microsoft/sbom-tool/blob/main/Dockerfile#L5

to:
RUN dotnet publish -f net8.0 -r $RUNTIME --self-contained true -p:DebugType=None -p:DebugSymbols=false -p:PublishSingleFile=true -p:IncludeAllContentForSelfExtract=true -o output
