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"}
jadpo checkcheck failed: 1 error, 1 file

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)
