toolchain.version_invalid

Application's jadpo: is not a major and minor version as text.

Area 1, Project layout and modules; not declinable; the next step is usually the agent's.

jadpo: is a release line: a major and a minor number as text. A release that only fixes something stays on its line, so the patch number is left out:

example
application {    jadpo: "0.1.0"}
text
error: `"0.1.0"` isn't a Jadpo version --> app.jadpo:2:12  |2 |     jadpo: "0.1.0"  |            ^^^^^^^ not a major and minor number as text  reason: `jadpo:` names the Jadpo release line the project is written for: its major and minor numbers as text, such as `"0.1"`. A release that only fixes something stays on its line, so the patch number is left out.  next: Write the line as its major and minor numbers in quotes, such as `jadpo: "0.1"` (agent)  rule: toolchain.version_invalid  help: https://jadpo.dev/docs/errors/toolchain.version_invalidcheck failed: 1 error, 1 file
