- Remove remnants of deprecated Scala parser - The following projects are now JPMS modules provided on system module-path (in components directory): - `ydoc-server` - `profiling-utils` - `syntax-rust-definition` - The contents of the aforementioned modules are excluded from both `runner.jar` and `runtime.jar` fat jars. - Suggestions are serialized and deserialized with our Persistance framework, rather than via the default Java OutputObjectWriter.

# sbt cheatsheet
|
|
|
|
This document contains various references and notes about sbt build definition.
|
|
One of the motivation for this document is that the
|
|
[official sbt documentation](https://www.scala-sbt.org/1.x/docs/index.html) is
|
|
not very informative.
|
|
|
|
### Resources
|
|
|
|
- [Official sbt documentation](https://www.scala-sbt.org/1.x/docs/index.html)
|
|
- [sbt.Keys](https://github.com/sbt/sbt/blob/1.10.x/main/src/main/scala/sbt/Keys.scala)
|
|
defines all the tasks and settings keys, including their documentation.
|
|
|
|
### Logging
|
|
|
|
- Get reference to the logger via `streams.value.log`.
|
|
- Log and error via `streams.value.log.error("My error")`
|
|
- Note that this will not cause the task to fail, this will only log an
|
|
`[error]` message. IF you want to fail a task, refer to
|
|
[Fail a task](#fail-a-task).
|
|
|
|
### Fail a task
|
|
|
|
- Simply throw a `java.lang.RuntimeException`.
|
|
- This will always work - it will crash the whole sbt process with the
|
|
RuntimeException. But it is not the official recommended way.
|
|
|
|
### Inspect tasks and settings
|
|
|
|
- `inspect tree project/assembly`
|
|
- This prints all the tasks and settings that will be executed when
|
|
`project / assembly` is run.
|
|
- It may be helpful to increase the width of the ASCI tree with
|
|
`set asciiGraphWidth := 150`.
|
|
- See `help inspect`.
|
|
|
|
## See all the transitive dependencies
|
|
|
|
- `print dependencyTree`
|
|
- This shows all the transitive dependencies for the default `Compile` scope.
|
|
- `print Test/dependencyTree`
|
|
- This show all the transitive dependencies for the `Test` scope.
|
|
|
|
### Debugging sbt tasks
|
|
|
|
- There is `--jvm-debug` cmd line option to sbt which allows to attach a
|
|
debugger to the sbt process.
|
|
- This option is not very handy, as you will still not be able to add a
|
|
breakpoint to various task definitions inside `build.sbt`, only to some
|
|
classes in the `project` directory. Moreover, once you run `reload`, the
|
|
debugging will not work for sure.
|
|
- This is because sbt internally compiles everything from `build.sbt` a
|
|
various anonymous classes and the debugger does not see their sources.
|
|
- It is better to either use `println` directly, or to use
|
|
`streams.value.log.info` to log messages.
|
|
|
|
### Exclude internal sbt project from a fat jar
|
|
|
|
- Fat jar for `fat-project` is assembled via the `fat-project / assembly` task.
|
|
- There is `fat-project / assembly / assemblyExcludedJars` setting which is of
|
|
type `Def.ClassPath`.
|
|
- To exclude internal `project` one must:
|
|
- Set `project / Compile / exportJars := true`. This ensures that
|
|
`project / Compile / exportedProducts` is a path to the jar.
|
|
- In `fat-project / assembly / assemblyExcludedJars` get the path to the
|
|
`project` jar via `project / Compile / exportedProducts`.
|
|
- Declare dependency on `project / Compile / packageBin` from
|
|
`fat-project / assembly`.
|
|
- Note that this is complicated because `assemblyExcludedJars` setting only
|
|
works if it points to an already existing jar file.
