Hi everyone. sbt 1.2.4 patch release is available.
project/build.properties as follows:
The sbt launcher will automatically resolve the sbt JARs based on what’s in
However, if you want to resolve them faster, you should use the installers. zip, tgz, and msi installers contain all the JAR files so the resolution completes from the
Note: Please run
clean after updating since sbt 1.2.4 includes a fix in the incremental compiler.
- Publishes JUnit reports using a compliant file name. #4343 by @ignasi35 at Lightbend
- Fixes Zinc to detect changes in private trait definitions. zinc#599 by @jvican at Scala Center
- Fixes IO.relativize’s handling of symbolic links. io#184 by @eed3si9n at Lightbend
On JDK 11 onwards the class location from a Java Module returns a jrt URL, for example
jrt:/java.base, which cannot convert to
java.io.File, but can be represented as an NIO
To work around this, sbt 1.2.4:
IO.classLocationFile[A: Manifest]: File
- brings back
IO.classLocation[A: Manifest]: URL
IO.classLocationPath[A: Manifest]: java.nio.file.Pathand
IO.classLocationFileOption[A: Manifest]: Option[File].
All of them return the directory, Java module, or the JAR containing the class file for type
A (as determined by an implicit
To improve the contribution experience to sbt and Zinc, and also to allow for better testing sbt team has been working on making nightly releases using Dbuild. The existing sbt launcher can already resolve artifacts out of sbt repo maven-snapshots, so we are now pointing the URL to the nightlies.
To find out the latest nightly build, go to sbt repo maven-snapshots and find the latest entry, or run the following shell script:
curl -s https://jenkins.scala-sbt.org/sbt-snapshots/org/scala-sbt/sbt/ | grep "<td>" | tail -n 1 | sed -e 's/<[^>]*>//g' -e 's/\/.*//' | read SBT_NIGHTLY && echo $SBT_NIGHTLY
This should output as follows:
To use that you can pass
-Dsbt.version=... from the commandline as follows:
sbt -Dsbt.version=1.3.0-bin-20181008T192044 sbt -Dsbt.version=$SBT_NIGHTLY
Note that it’s going to hit the Jenkins server instead of Maven Central so it might take a minute or two to resolve sbt JARs.
sbt 1.2.4 was brought to you by 7 contributors. Eugene Yokota, Jorge Vicente Cantero (jvican), Chris Birchall, Adam Kasztenny, Dima Kotobotov, Flash Sheridan, Ignasi Marimon-Clos. Thank you!
Thanks to everyone who’s helped improve sbt and Zinc 1 by using them, reporting bugs, improving our documentation, porting builds, porting plugins, and submitting and reviewing pull requests.
For anyone interested in helping sbt, there are many avenues for you to help, depending on your interest.
