v0.103.0

[maxandersen]

A new release and this one is a silent but beautiful one.

First there is a bunch of small fixes after last release custom JDK support introduced some regressions - like breaking Groovy support; but that is now back. Thanks for all the feedback!

export fat jar

jbang export fatjar now exists. It merges all dependencies into a single combined jar allowing you to easily copy/distribute as a single command . It merges overlapping META-INF/services and for most things that seem sufficient.

If you use it and things does not work, open issues and we can look at improving it.

native image now honored by alias

@kanha-gupta contributed his first fix making it so --native for building native images
works for aliases.

jbang will now get latest version, reducing need to use --fresh

Since forever jbang aliases were defined in a catalog and if that catalog was updated
AFTER you fetched something the first time you would not get the latest updates unless you used --fresh.

Now @quintesse implemented proper cache eviction so that

a) when you run an alias jbang newcommand@somecatalog and that newcommand is not found locally then
jbang will now force reload the catalog to see if there is a new command.

b) By default every 12 hours the cache will be refreshed, meaning updates to alias catalogs (not just new ones will automatically be downloaded)

This allows for much smoother updates and ensuring users have the latest and greatest.

If for some reason you as a user do NOT want that (i.e. you really want zero updates) you have multiple options dependent on your usecase:

• To get similar behavior as before, set cache-evict to never, i.e. jbang config set cache-evict never
• run with --offline then jbang will not do any remote requests, including cache updates.
• install/use aliases with a specific version or even SHA. i.e. jbang cmd@myorg//2.0 or jbang kill@quarkusio//5b58242 to lock in a specific alias.
