3 | | -# This is a wrapper script, that automatically selects or downloads Mill from Maven Central or GitHub release pages. |
4 | | -# |
5 | | -# This script determines the Mill version to use by trying these sources |
6 | | -# - env-variable `MILL_VERSION` |
7 | | -# - local file `.mill-version` |
8 | | -# - local file `.config/mill-version` |
9 | | -# - `mill-version` from YAML fronmatter of current buildfile |
10 | | -# - if accessible, find the latest stable version available on Maven Central (https://repo1.maven.org/maven2) |
11 | | -# - env-variable `DEFAULT_MILL_VERSION` |
12 | | -# |
13 | | -# If a version has the suffix '-native' a native binary will be used. |
14 | | -# If a version has the suffix '-jvm' an executable jar file will be used, requiring an already installed Java runtime. |
15 | | -# If no such suffix is found, the script will pick a default based on version and platform. |
16 | | -# |
17 | | -# Once a version was determined, it tries to use either |
18 | | -# - a system-installed mill, if found and it's version matches |
19 | | -# - an already downloaded version under ~/.cache/mill/download |
20 | | -# |
21 | | -# If no working mill version was found on the system, |
22 | | -# this script downloads a binary file from Maven Central or Github Pages (this is version dependent) |
23 | | -# into a cache location (~/.cache/mill/download). |
