• Update vendor licenses - Automatically updated contents in the LICENSES directory after the update-vendor-licenses.sh script is executed.
• Update client generation tools, remove k8s dependency, fix lint issues - Some file modifications caused by updating go and K8s versions (Need to focus on).
• Solved the vendor check to fail - Solved the problem that git does not recognize uppercase and lowercase letters in file names, causing vendor check to fail.

Could you also help change the version of the controller-gen tool in the Makefile to v0.15.0 to keep it consistent with Kubeedge?

Why was golint removed and revive introduced in the linters?

[WillardHu]

golint is no longer supported in golangci-lint

[tangming1996]

Was the following if logic removed because Sedna uses Go modules, thus eliminating the need for GOPATH?

if ! [[ "${GOPATH}/src/${SEDNA_GO_PACKAGE}/" -ef "${SEDNA_ROOT}/" ]]; then
    # Copy generated code into SEDNA_ROOT
    echo "Warning: ${SEDNA_ROOT} not included in $GOPATH which is required by code-gen"
    echo "Moving generated code from ${GOPATH}/src/${SEDNA_GO_PACKAGE}/pkg/ to ${SEDNA_ROOT}/"
    rsync -a ${GOPATH}/src/${SEDNA_GO_PACKAGE}/pkg/{client,apis} ${SEDNA_ROOT}/pkg
    if [ $? -eq 0 ]; then
        echo "Copy successful!"
        rm -rf ${GOPATH}/src/${SEDNA_GO_PACKAGE}/pkg/{client,apis}
    else
        echo "Error during copy of the generated code!" >&2
    fi
fi

The new versions of client-gen, lister-gen and informer-gen tools can specify the output directory through the --output-dir flag.
