### Printing trees
E.g. to print the dependency tree of `io.circe:circe-core:0.4.1`,
```
$ coursier resolve -t io.circe:circe-core_2.11:0.4.1
Result:
└─ io.circe:circe-core_2.11:0.4.1
├─ io.circe:circe-numbers_2.11:0.4.1
| └─ org.scala-lang:scala-library:2.11.8
├─ org.scala-lang:scala-library:2.11.8
└─ org.typelevel:cats-core_2.11:0.4.1
├─ com.github.mpilquist:simulacrum_2.11:0.7.0
| ├─ org.scala-lang:scala-library:2.11.7 -> 2.11.8
| └─ org.typelevel:macro-compat_2.11:1.1.0
| └─ org.scala-lang:scala-library:2.11.7 -> 2.11.8
...
```
From SBT, with sbt-coursier enabled, the command `coursierDependencyTree` prints the dependency tree of the various sub-projects,
```
> coursierDependencyTree
io.get-coursier:coursier_2.11:1.0.0-SNAPSHOT
├─ com.lihaoyi:fastparse_2.11:0.3.7
| ├─ com.lihaoyi:fastparse-utils_2.11:0.3.7
| | ├─ com.lihaoyi:sourcecode_2.11:0.1.1
| | | └─ org.scala-lang:scala-library:2.11.7 -> 2.11.8
| | └─ org.scala-lang:scala-library:2.11.7 -> 2.11.8
| ├─ com.lihaoyi:sourcecode_2.11:0.1.1
| | └─ org.scala-lang:scala-library:2.11.7 -> 2.11.8
| └─ org.scala-lang:scala-library:2.11.7 -> 2.11.8
├─ org.jsoup:jsoup:1.9.2
...
```
Note that this command can be scoped to sub-projects, like `proj/coursierDependencyTree`.
The printed trees highlight version bumps, that only change the patch number, in yellow. The `2.11.7 -> 2.11.8` above mean that the parent dependency wanted version `2.11.7`, but version `2.11.8` landed in the classpath, pulled in this version by other dependencies.
They highlight in red version bumps that may not be binary compatible, changing major or minor version number.
### Generating bootstrap launchers
The `coursier bootstrap` command generates tiny bootstrap launchers (~12 kB). These are able to download their dependencies upon first launch, then launch the corresponding application. E.g. to generate a launcher for scalafmt,
```
$ coursier bootstrap com.geirsson:scalafmt-cli_2.11:0.2.3 -o scalafmt
```
This generates a `scalafmt` file, which is a tiny JAR, corresponding to the `boostrap` sub-project of coursier. It contains resource files, with the URLs of the various dependencies of scalafmt. On first launch, these are downloaded under `~/.coursier/boostrap/com.geirsson/scalafmt-cli_2.11` (following the organization and name of the first dependency - note that this directory can be changed with the `-D` option). Nothing needs to be downloaded once all the dependencies are there, and the application is then launched straightaway.
### Credentials
To use artifacts from repositories requiring credentials, pass the user and password via the repository URL, like
```
$ coursier fetch -r https://user:pass@company.com/repo com.company:lib:0.1.0
```
From SBT, add the setting `coursierUseSbtCredentials := true` for sbt-coursier to use the credentials set via the `credentials` key. This manual step was added in order for the `credentials` setting not to be checked if not needed, as it seems to acquire some (good ol') global lock when checked, which sbt-coursier aims at avoiding.
### Extra protocols
By default, coursier and sbt-coursier handle the `http://`, `https://`, and `file://` protocols. It should also be fine
by protocols supported by `java.net.URL` (not thoroughly tested). Support for other protocols can be added via plugins. [coursier-s3](https://github.com/rtfpessoa/coursier-s3), a plugin for S3, is under development, and illustrates how to write such plugins.
## Limitations ## Limitations
#### Inter-project repository in the SBT plugin is a bit naive
**Fixed in 1.0.0-M13**
The inter-project repository is the pseudo-repository, nesting the metadata
of sub-projects. It gets confused in at least these two cases:
- two sub-projects have the same organization and module name,
- a sub-project depends on a released version of another sub-project, possibly transitively.
The problem with it is that it doesn't look at the real sub-projects graph. It
just trusts SBT to put dependencies between projects in the library
dependencies.
So if a link appears transitively, with a sub-project depending on
a released version of a sub-project (second point above), the coursier SBT plugin will
think there's a dependency between the sub-projects. Thus it will trust
SBT to put the second project build products on the classpath.
But SBT knows there's no such link, so it just doesn't put them.
The second point happens for the `readme` sub-project of Ammonite, for example,
which transitively depends on a released version of `ammonite-ops`, itself also
built by the `ops` sub-project.
