CaPyCLI - Frequently Asked Questions

What is the difference between CreateReleases and CreateComponents?

SW360 knows components and releases. Releases are specific versions of a component. Some people take more care when choosing component names than others. Assume the component spring-boot already exists on your SW360 instance. Then it would not be the best idea when someone adds additional components Spring Boot, spring_boot or Apache SpringFramework Boot.
CreateReleases allows only to create new releases of an existing component. CreateComponents will also create missing components. So be careful when using CreateComponents.

Why are there sometimes multiple entries of a components in the SBOM after mapping?

CaPyCLI has different modes for mapping an existing SBOM to the data available on SW360. One mode list all available releases of a component if the matching release does not exist on SW360.

Example: Assume you are looking for the release Tethys.Logging, 1.4.3. When CaPyCLI bom map displays

Match by name, Tethys.Logging, 1.4.3 => Tethys.Logging, 1.6.1 (and 5 others)

then the resulting SBOM will contain

  • Tethys.Logging, 1.4.3 with the mapping code 9-no-match.
  • Tethys.Logging, 1.6.1 with the mapping code 5-candidate-match-by-name
  • 5 more releases of Tethys.Logging with the mapping code 5-candidate-match-by-name

=> Depending on the mapping result a review/editing of the resulting SBOM is required!

What is 'Granularity'?

In a software project you use the libraries you need. You pull them from the packet manager of your software ecosystem (NuGet, Maven, NPM, PyPi, etc.). For license compliance analysis you need the source code of these binaries. Often many binaries are built out of the same source code. Granularity is about have the appropriate data on SW360. At Siemens we prefer to the the source code granularity, i.e. we have components like Angular or spring-boot and not separate components for @angular/animations/browser, @angular/compiler or spring-boot-actuator-autoconfigure and spring-boot-starter-aop.

My Write Token does not work

Depending in your SW360 configuration, your write token might be an OAuth2 token.
In this case you also have to use the -oa switch to tell CaPyCLI that this is an OAuth2 token.
