-----------------------------------
Summary: camel-jbang - camel generate rest --dto does not write
the DTOs of a package with more than one name, or when they exist
Key: CAMEL-26442
URL: https://issues.apache.org/jira/browse/CAMEL-26442
Project: Camel
Issue Type: Bug
Components: camel-jbang
Reporter: Claus Ibsen
Fix For: 4.24.0
{{camel generate rest --dto}} generates the DTOs into a temporary directory,
and moves the directory of the package to the working directory with
{{File.renameTo}} ({{CodeRestGenerator.generateDto}}). That fails, and the DTOs
are not written:
* when the package has more than one name and its parent directory does not
exist ({{--package=org.acme}} without a directory {{org}}): {{renameTo}} does
not create parent directories;
* when the directory of the package exists, such as when the command runs a
second time;
* when the temporary directory is on another file system than the working
directory (such as a {{/tmp}} on tmpfs).
The command then prints {{ERROR: Failed to move generated DTOs to org/acme}}
but exits with {{0}}, and leaves the temporary {{gendto*}} directory behind
(also when the move works, as only its subdirectory is moved).
Reproduce (with
{{components/camel-openapi-java/src/test/resources/petstore-v3.json}}):
{code}
camel generate rest --input=petstore-v3.json --dto --output=rest.yaml
--package=org.acme
{code}
It writes {{rest.yaml}} only, and exits with 0. With {{mkdir org}} first it
writes the 8 DTOs into {{org/acme}}; running it again fails the same way. The
default package ({{model}}) works the first time.
Expected: the DTOs are written (creating the directories, replacing the files
of an earlier run), the temporary directory is removed, and a failure exits
with a non-zero exit code.
Found while checking CAMEL-26441.
