Conversation
Three changes to the NuGet/dotnet FlexPack command, all narrowing what jf does on the user's behalf. Let the native client perform the upload. FlexPack's contract is that the native tool does the work and jf observes it, but push was intercepted and sent through the Artifactory upload service instead. The comment justifying that cited a 401 from 'dotnet nuget push' against a V3 index.json. That 401 is specific to credentials carried IN the source URL, where the service-index fetch goes out unauthenticated; supplying them through the config file avoids it entirely. Verified against Artifactory with nuget.exe 6.6.2 and dotnet SDK 10.0.302: both push successfully. The bypass and its seven now-unreachable helpers are removed. Pass credentials in the environment rather than writing them to disk. The temp nuget.config no longer carries a <packageSourceCredentials> block; the native client reads NuGetPackageSourceCredentials_<source> from its environment instead. This removes the persistence risk - a signal that skips cleanup can no longer strand a token in a file - while keeping the secret out of argv, which is world-readable via ps. It is not secrecy: the value is still visible to same-user processes, and the code says so rather than overclaiming. The config now also carries defaultPushSource, so the push finds its target without jf appending -Source/--source to the user's command line. Keeping the target in configuration rather than argv means the native client is invoked exactly as the user wrote it, and avoids branching on per-toolchain flag spelling. Stamp vcs/ci properties on pushed artifacts. Push recorded only build.name, build.number and build.timestamp, so an artifact knew which build produced it but not which commit, branch or pipeline run. Routing through civcs.MergeWithUserProps - the helper Terraform and the other FlexPack managers already use - closes that gap. It is a no-op outside a repository or when the properties are disabled.

🌐 Web query:
NuGet dotnet nuget push --api-key without --source default push source behavior nuget.exe
💡 Result:
For both the dotnet CLI (dotnet nuget push) and the NuGet CLI (nuget.exe), the --source (-s/-src) parameter is mandatory unless a DefaultPushSource is configured in your NuGet.config file [1][2][3]. If you omit the --source parameter and a DefaultPushSource is not defined, the push command will fail because it does not have a destination for the package [1][4]. Behavior Summary: 1. Mandatory Source: Starting with NuGet 3.4.2, --source is a required parameter for the push operation unless a default is specified in the configuration [1][2]. 2. DefaultPushSource: You can set a default destination by adding a DefaultPushSource entry to your NuGet.config file [1][2]. When this is set, you can run the push command without explicitly providing the --source argument, and the client will use the configured default [1][5]. 3. API Key Usage: When you provide an --api-key (or -k), the tool uses that key to authenticate the request against the determined source (either the one provided via --source or the DefaultPushSource defined in your config) [1][6]. The CLI follows a specific order of precedence for credentials: it checks the command-line argument first, then environment variables, and finally the NuGet.config file [6]. In short, if you do not specify --source, the command relies entirely on the DefaultPushSource setting in your configuration files to identify where to push the package [1][3].

Preserve the configured source for API-key-only pushes.
When the caller provides --api-key without --source, hasNativeAuthOverride makes shouldPushViaNativeClient return false. The condition at line 145 then skips the temporary configuration, although the native client still runs. Without a user-configured defaultPushSource, both nuget.exe and dotnet nuget push can fail because they have no destination.
Create the temporary configuration for this path with the Artifactory source and defaultPushSource, but leave credentialEnv empty so the caller-provided API key remains the only injected credential. Add regression coverage for both clients with no existing NuGet configuration.

The JWT-shaped string in TestCredentialEnvEntry is a fixture asserting that an access token reaches the credential entry unaltered, not a credential. Annotated rather than obscured, so the test still shows the exact shape it is checking. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

What
Three changes to the NuGet/dotnet FlexPack command, all narrowing what jf does on the user's behalf.
1. Let the native client perform the upload
FlexPack's contract is that the native tool does the work and jf observes it — but
pushwas intercepted and routed through the Artifactory upload service instead. The comment justifying that cited a 401 fromdotnet nuget pushagainst a V3index.json.That justification doesn't hold. The 401 is specific to credentials carried in the source URL, where the service-index fetch goes out unauthenticated. Supplying them through a config file avoids it entirely. Tested against Artifactory before changing anything:
dotnetSDK 10.0.302dotnetSDK 10.0.302<packageSourceCredentials>in confignuget.exe6.6.2-Source <v3 index> -ApiKey user:tokennuget.exe6.6.2<packageSourceCredentials>in configBoth clients push fine. The bypass and its seven now-unreachable helpers are removed (−318 lines), and the
if/elsedispatch collapses to "run the native client".A user's own
-Source/-ApiKeystill wins, unchanged.2. Credentials travel in the environment, not on disk
The temp
nuget.configno longer carries a<packageSourceCredentials>block. The native client readsNuGetPackageSourceCredentials_<source>from its environment instead.This removes the persistence risk — a signal that skips cleanup can no longer strand a token in a file — while keeping the secret out of
argv, which is world-readable viaps.It is not secrecy: the value is still readable by same-user processes (
ps -E,/proc/<pid>/environ). The code comment says exactly that rather than overclaiming.The config now also carries
defaultPushSource, so the push finds its target without jf appending-Source/--sourceto the user's command line. Keeping the target in configuration rather than argv means the native client is invoked exactly as the user wrote it, and avoids branching on per-toolchain flag spelling.3. Stamp

One ordering trap worth noting
shouldPushViaNativeClient()is computed before credential injection. Injection appends toc.args, andhasNativeAuthOverridetreats a--sourceas a user override — so evaluating afterwards would make jf misread its own flag as user intent. The comment records why.Testing
TestShouldPushViaNativeClient— 5 cases: both toolchains native, user auth override respected, non-push subcommands unaffected, missing server/repo falls throughTestCredentialEnvEntry— format, source-name keying (a mismatch silently 401s), verbatim token passthroughTestTempConfigCarriesNoSecret— writes a real temp config with a known password and asserts the file contains no password, noClearTextPassword, nopackageSourceCredentials, while still declaring the source; then that cleanup removes the file and clears the credentialgofmt,go build ./...,go vet,golangci-lint— clean, includingunusedafter the deletionsjf dotnet nuget pushandjf nuget pushboth upload via their native client with build-info and properties intactTradeoff being accepted
The removed upload-service path provided checksum-optimised deploys (skip transfer when the blob exists), jf's retry logic, and JFrog proxy handling. Native push has none of these — it always uploads the bytes. For large or frequently re-pushed packages that is a real difference, and it is a deliberate choice in favour of not interfering with the native client.
