Some resource gets always checked and downloaded again from the central repo

[halloleo]

I have a scala-cli project which uses

• com.lihaoyi::mainargs:0.7.7
• com.lihaoyi::pprint:0.9.0
• com.outr::scribe::3.17.0

When run it with scala-cli run . -- my args I always get the informational output

Checking http://ourserver.com/nexus/repositories/central/com/lihaoyi/pprint_3/
Checked http://ourserver.com/nexus/repositories/central/com/lihaoyi/pprint_3/
Downloading http://ourserver.com/nexus/repositories/central/com/lihaoyi/pprint_3/
Downloaded http://ourserver.com/nexus/repositories/central/com/lihaoyi/pprint_3/

even after the second or third time I run the command (without changes to the source!) when -- as I expect -- everything should already be downloaded.

Why is this and how can I suppress this output?

[Gedochao]

The output is coming from coursier.
I'm not actually sure if something is being downloaded, or is it just coursier being verbose while checking if things are in place.
Is there an actual slowdown, or is this being printed with no delay?
I can see you're using a proxy/custom repo (ourserver.com/nexus), perhaps that's what prints more logs.

I can't seem to reproduce locally (Scala CLI 1.9.1, MacOS M1 build).

Sanity check, @halloleo can you try running your project with a nightly Scala CLI build?
We have bumped to the newest coursier version recently, the behaviour might be different.

Try:

scala-cli --cli-version nightly run . -- my args

And let me know if this keeps happening.

[halloleo]

Thanks heaps for chiming in. It is not easy for my to run the nightly build, because the machine is in a network without internet connection (that's why we have our own Maven repo). the machine cannot connect to github and thesorts. only the nexus repos are available.

That's why my scala-cli is a downloaded binary. It is version 1.2.2. Maybe updating to a recent stable version sorts things already out.

What is the easiest way to get a x86_64 binary of, say, version 1.9.1 for download? (I got my version a year ago via an rpm download.)

[Gedochao]

Just download it from the tag: https://github.com/VirtusLab/scala-cli/releases/tag/v1.9.1
Nightly launchers can be found here, under the nightly tag: https://github.com/VirtusLab/scala-cli/releases/tag/nightly
And yeah, 1.2.2 is super old. Please update to something more recent before raising an issue 😅

[halloleo]

Just tried to run V 1.9.1 (from the rpm) on the machine I have the resource troubles, it doesn't seem to work, because this version of scala-cli need GLIBC_2.32 or above.

The machine in question has only GLIBC_2.17. What is the latest scala-cli version which runs on GLIBC_2.17?

Or can I download another package instead of the RPM package which would work (independently of the old GLIBC_2.17)?

[Gedochao]

What is the latest scala-cli version which runs on GLIBC_2.17?

If you need the standard native image, then you'd have to go back all the way to Scala CLI v1.6.2. Which is a bit old as well, even if less old than v1.2.2

Or can I download another package instead of the RPM package which would work (independently of the old GLIBC_2.17)?

I believe you can try one of the static or mostly static launchers, if I recall correctly, it could be a solution.
I suppose they're a bit of a secret feature, I should add a mention about them in the docs 😅
We upload them under each tag.

Mostly static v1.9.1:
https://github.com/VirtusLab/scala-cli/releases/download/nightly/scala-cli-x86_64-pc-linux-mostly-static.gz

Static v1.9.1:
https://github.com/VirtusLab/scala-cli/releases/download/nightly/scala-cli-x86_64-pc-linux-static-sdk.zip
https://github.com/VirtusLab/scala-cli/releases/download/nightly/scala-cli-x86_64-pc-linux-static.gz

If even that doesn't work, you can always use the JVM launcher (bootstrapped fat JAR). You'll need Java 17 or above to run that (if you run with an older Java (but no older than 11), it will try to download the JDK to re-run itself).
https://scala-cli.virtuslab.org/install#bootstrapped-standalone-fat-jar
https://github.com/VirtusLab/scala-cli/releases/download/v1.9.1/scala-cli.jar <- here is the v1.9.1 one.
https://github.com/VirtusLab/scala-cli/releases/download/nightly/scala-cli.jar <- here is the nightly.

Let me know what worked (if anything).

[halloleo]

Thanks heaps for the links! scala-cli-x86_64-pc-linux-static.gz worked.

Plus, I do not seem to get the "Checking... " and "Downloading...," lines for pprint_3 anymore. 😃👍🙏
