Ricardo Martinez created CAMEL-26370:
----------------------------------------
Summary: `camel export --local-kamelet-dir=<dir1>,<dir2>` silently
produces a broken export when more than one directory is supplied on the 4.22.x
branch.
Key: CAMEL-26370
URL: https://issues.apache.org/jira/browse/CAMEL-26370
Project: Camel
Issue Type: Bug
Reporter: Ricardo Martinez
h2. Description
The same two bugs present in the main/4.23 regression (see related issue) also
exist verbatim in {{ExportBaseCommand.copySourceFiles()}} on the
{{camel-4.22.x}} maintenance branch.
On 4.22.x the {{camel run --runtime=camel-main}} code path is *not* affected
because commit {{935f581a8a59}} (CAMEL-24659) — which routed {{camel run
--runtime=camel-main}} through the export pipeline — was *never backported* to
that branch. In 4.22.x that command still runs in-process via {{KameletMain}},
bypassing {{copySourceFiles()}} entirely.
However, the *{{camel export}}* sub-command (all runtimes: camel-main, quarkus,
spring-boot) *does* call {{copySourceFiles()}} on 4.22.x, so any user running:
{code:bash}
camel export --local-kamelet-dir=/path/to/dir1,/path/to/dir2 ...
{code}
will get a project where the kamelet files are missing — the copy step silently
fails to resolve the correct source path.
h3. Root Cause
Identical to the main/4.23 issue:
*Bug 1* — {{getScheme()}} is called on the entire comma-joined
{{LOCAL_KAMELET_DIR}} string. Only the scheme from the first entry is stripped;
subsequent entries retain their {{file:}} prefix.
*Bug 2* — {{Paths.get(localKameletDir, f + ".kamelet.yaml")}} is called with
the still-comma-joined string, producing a non-existent path that contains a
literal comma.
h3. Affected File (on {{camel-4.22.x}})
{{dsl/camel-jbang/camel-jbang-core/src/main/java/org/apache/camel/dsl/jbang/core/commands/ExportBaseCommand.java}}
— method {{copySourceFiles()}}, lines ~874–878 (scheme stripping) and ~944–946
(path construction).
h3. Relationship to Main Issue
This issue covers the *{{camel-4.22.x}} backport* of the same fix. The fix on
main replaces the single {{localKameletDir}} string with a {{List<String>}},
strips the scheme per element, and searches directories in order. The same
change applies cleanly to {{camel-4.22.x}}.
h3. Workaround (until fixed)
Pass only a single directory to {{--local-kamelet-dir}} — the most specific one
(e.g. the {{kamelets/}} subdirectory).
