clear the Coursier cache by deleting the C:\Users\-username-\AppData\Local\Coursier\cache\ directory clear the project by deleting the ./target and ./project/target directories update the offending Cucumber dependencies to 6.0.0-RC2 These would mean that the resolution wasn't able to get metadata about some dependencies. The java-home command prints the Java home of a JVM, like We're using the Cache.file method, that can also be given a Logger (for more feedback) and a custom thread pool. For more information, see our Privacy Statement.

The java and java-home commands use the JVM setup on your system by default. they're used to gather information about the pages you visit and how many clicks you need to accomplish a task. Note that it can be more convenient to pass arguments to native-image via a native-image.properties resource rather than on the command-line, if adding it to the original application sources is an option for you. The high level API of coursier aims at being as simple to use as its CLI, with sensible defaults in particular, while retaining the purity of the low-level API. To get started with the high level API, add the settings below to build.sbt. Relying on those URLs, which are specific to the current machine / user, would make the bootstrap non-portable. It allows to do one resolution step. I've still only seen this in artifacts resolved from this specific Nexus. in my ~/.sbt/0.13/coursier.sbt and it works. Optionally, one can call withRepositories to set all the repositories at once, wiping the default ones and any previously passed one. To circumvent that, such local artifacts are embedded as resources in the bootstraps, like standalone bootstraps do. These can be disabled with --default-assembly-rules=false. Using in ThisBuild doesn't work for some reason, but that setting does work. on OS X, ~/Library/Caches/Coursier/v1. basically what's strange is that only mvn-releases will have the netty-codec-http2 while all the others won't have netty-codec-http2 so maven-metadata.xml is of course empty. These are also a JAR, and contain the same shell preamble as standard and standalone bootstraps. If a JVM is already installed on your system, the java command simply calls it, just as if you called it yourself: Likewise, the java-home command prints its base directory, which can look like. New Version: 2.0.0-RC6-25: Maven; Gradle; SBT; Ivy; Grape; Leiningen; Buildr It uses the index of jabba to know where to download JVM archives, and assumes AdoptOpenJDK if only a version is passed.

I can also just delete this specific artifact and it will generally work.

Learn more. It is an IvyRepository, picking things under ~/.ivy2/local. the coursier.jvm.cache Java property. By default, downloads happen in a global fixed thread pool (with 6 threads, allowing for 6 parallel downloads), but you can supply your own thread pool to Cache.fetch. The first module, "io.get-coursier" %% "coursier-core" % "2.0.0-RC6-27+11-59bf7739-SNAPSHOT", contains among others, definitions, mainly in Definitions.scala, Resolution, representing a particular state of the resolution, and ResolutionProcess, that expects to be given metadata, wrapped in any Monad, then feeds these to Resolution, and at the end gives you the final Resolution, wrapped in the same Monad it was given input.
Of course, Ivy isn't immune to this either, so I think one of two things are happening. It's not deterministic, but I can reproduce it.

All arguments from the first it doesn't recognize are passed as is to the java process it starts. Note: There is a new version for this artifact. coursier.Resolve allows to run resolutions, that is finding all the transitive dependencies of some initial dependencies (while reconciling their versions at the same time). "/home/alex/.cache/coursier/jvm/adopt@1.11.0-6". with the same methods as coursier.Resolve. The second module, "io.get-coursier" %% "coursier-cache" % "2.0.0-RC6-27+11-59bf7739-SNAPSHOT", is precisely in charge of fetching these input metadata. Specifically: verizon.inf.delorean:core_2.11:1.1.+. Correction to the previous: I've now seen it with both Nexuses.

the generated scalafmt file is a JAR containing a tiny Java application, along with a URL list as a resource (the URLs of the JARs of scalafmt, in coursier/bootstrap/launcher/bootstrap-jar-urls). on OS X, ~/Library/Caches/Coursier/v1. Linking flags during the linking phase can be adjusted via LDFLAGS in the environment. It uses its own coursier.util.Task as a Monad to wrap them. If you prefer, you can also call withDependencies, that accepts a Seq[Dependency], and wipes any previously passed dependency.

Both IvyRepository and MavenRepository are case classes, so that it's straightforward to specify one's own repositories. We use optional third-party analytics cookies to understand how you use GitHub.com so we can build better products. More details here. By clicking “Sign up for GitHub”, you agree to our terms of service and This entirely relies on metadata, that is POM or maven-metadata.xml files for Maven repositories, and ivy.xml files for Ivy repositories. You signed in with another tab or window. Either Ivy is more forgiving of checksum failure on the artifact-level metadata, or it simply attempts to re-fetch the metadata or its checksum (or both) a few times in the event of a checksum failure. This sync has a (sometimes significant!) It uses its own coursier.util.Task as a Monad to wrap them. Same thing started happening for me on Windows 10 on an ordinary user account (not system/virtual). These are not of very common use in Scala, although sbt uses them a bit. regression: fastparse failing because it uses coursier now. coursier.Fetch resolves dependencies, then fetches their artifacts. The same thing seems to happen with a "vanilla" account. Additionally, if I curl the maven-metadata.xml.sha1 file which is also in the right place in our Nexus, I get a file which contains the right hash. The first one, Cache.ivy2Local, is defined in coursier.Cache, itself from the coursier-cache module that we added above.
It also fetches artifacts (JARs, etc.). @alexarchambault Still seeing the checksum error, even with okhttp. These are even more lightweight than standard bootstraps, but are only meant to be used by the same user / on the same machine. 1.0.0-M14 (which should be released in a few hours) will also ship with an optional okhttp plugin, that can be enabled by adding. We use essential cookies to perform essential website functions, e.g. Lastly, the run method runs the whole resolution until its end. Hi , I trying to cache the scala & coursier dependencies. We'll create a function of type Seq[(Module, String)] => F[Seq[((Module, String), Either[Seq[String], (Artifact.Source, Project)])]]. It has various methods allowing to process dependencies, most notably minDependencies, returning a set of dependencies (with redundant dependencies stripped).

Unlike the Ivy repositories which involve customisable patterns to point to the underlying metadata and artifacts, the paths of these for Maven repositories all look alike, like for any particular version of the standard library, under paths like this one. @alexarchambault Any suggestions as to what I should be looking for? Inversely, disable generating it on Windows with --bat=false. This monad can be changed by changing the cache upfront, like. It then loads them from the coursier cache in a java.net.URLClassLoader, and starts the actual application from it. As of writing this, the default JVM is the latest AdoptOpenJDK 8 from the JVM index.

Sorry to spam this issue… I've finally managed to see the issue without coursier. sbt-coursier sbt-coursier ensures one's dependencies are fetched via coursier rather than by sbt itself, that relies on its own custom version of Ivy. Note that sbt-coursier itself is still fetched by sbt. The java and java-home commands fetch and install JVMs. bootstrap puts the same preamble as standard bootstraps in assemblies, Some of the application JARs may contain files with the same path. Common ones like Central like here, or the repositories from Sonatype, are Maven repositories.

Already on GitHub?

This kind of repository involves a so-called pattern, with various properties. A slightly more sophisticated solution would involve some retries. Shorter syntaxes are supported. sbt.coursier.home: Directory: CoursierDependencyResolution.defaultCacheLocation (in 1.3+) Location of coursier artifact cache, where the default is defined by Coursier cache resolution logic. Learn more, We use analytics cookies to understand how you use our websites so we can make them better, e.g. This command automatically fetches and extracts a GraalVM Community edition archive, like the java command of coursier does, then uses it to call native-image. I really don't know if it's Coursier downloading the wrong thing, or our Nexus serving the wrong thing, or some combination of the two, but it's weird. If these two connections are load balanced to separate instances while the instances are out of sync, Coursier will acquire either stale metadata or a stale checksum. Calling process on start above gives a ResolutionProcess, that drives the resolution. The default repositories are the Ivy2 local repository (only on the JVM) and Maven Central. they're used to log you in. @djspiewak thx for your explanation but I only have one Nexus instance so I don't think it's the root cause for me. These JARs are downloaded to / picked from the cache of coursier. If the version doesn't exactly match an available one, it is assumed it corresponds to an interval. Coursier attempts to store its cache in null/Coursier/v1 subfolder of the build folder, instead of AppData/Local for the corresponding account. Have a question about this project? So one instance will have a revised artifact-level metadata XML file, while the other will still have the old file. The coursier project welcomes contributions from anybody wishing to participate. If none of these methods finds a JVM, it is assumed no JVM was installed prior to running cs java or cs java-home. This page describes the new high level API of coursier, being added since 1.1.0-M10. :-) Once this situation arises by the way (which is far more often than not with artifacts resolved from this Nexus), it never seems to fix itself. The java command runs them too.

First, the workaround: Put that in every build.sbt file, or add it to the default settings of every project.

:-). Like for Resolve, fetching can be (eagerly) run in the background by calling future rather than run, like, Like for Resolve, fetching can be (lazily) run in the background by calling io rather than run, like. Certainly not as frequent, but it's happening.

The account thing seems to be a red herring.

With Coursier, the metadata for that artifact is effectively permanently corrupted (well, until the refresh timeout), since from Coursier's perspective, the metadata has already been fetched!
