error during sbt execution: java.nio.channels.overlappingfilelockexception from windows command prompt - sbt

Question

I'm trying to install sbt on windows 7 but testing it, I get the following error:
java.nio.channels.OverlappingFileLockException

Error during sbt execution: java.nio.channels.OverlappingFileLockException
which seems related to the fact that I do have access to my remote HOME drive according to this post:
https://groups.google.com/forum/#!topic/simple-build-tool/lJvOvZ5RUwE
I tried to follow what they suggest, but I have never found any sbt.boot.properties file. I have also tried to overwrite the boot and working dir via:
sbt -sbt-dir C:\my\new\home -sbt-boot C:\my\new\home
Would any of you have gone through all these problems and could have a step-by-step recipy to solve that ?

Answer 1

Ok so I had the same problem. The sbt.boot.properties file resides inside the sbt-launch.jar archive. Open it with an archive tool like winzip or 7zip and then look in the folder /sbt and you will see the sbt.boot.properties file.
The current version looks like this
[scala]
version: ${sbt.scala.version-auto}
[app]
org: ${sbt.organization-org.scala-sbt}
name: sbt
version: ${sbt.version-read(sbt.version)[0.13.6]}
class: ${sbt.main.class-sbt.xMain}
components: xsbti,extra
cross-versioned: ${sbt.cross.versioned-false}
resources: ${sbt.extraClasspath-}
[repositories]
local
typesafe-ivy-releases: https://repo.typesafe.com/typesafe/ivy-releases/, [organization]/[module]/[revision]/[type]s/[artifact](-[classifier]).[ext], bootOnly
maven-central
[boot]
directory: ${sbt.boot.directory-${sbt.global.base-${user.home}/.sbt}/boot/}
[ivy]
ivy-home: ${sbt.ivy.home-${user.home}/.ivy2/}
checksums: ${sbt.checksums-sha1,md5}
override-build-repos: ${sbt.override.build.repos-false}
repository-config: ${sbt.repository.config-${sbt.global.base-${user.home}/.sbt}/repositories}
Make sure you add the property lock in the [boot] section or you will get another error. So eventually it should look like this:
[scala]
version: ${sbt.scala.version-auto}
[app]
org: ${sbt.organization-org.scala-sbt}
name: sbt
version: ${sbt.version-read(sbt.version)[0.13.6]}
class: ${sbt.main.class-sbt.xMain}
components: xsbti,extra
cross-versioned: ${sbt.cross.versioned-false}
resources: ${sbt.extraClasspath-}
[repositories]
local
typesafe-ivy-releases: https://repo.typesafe.com/typesafe/ivy-releases/, [organization]/[module]/[revision]/[type]s/[artifact](-[classifier]).[ext], bootOnly
maven-central
[boot]
directory: ${sbt.boot.directory-${sbt.global.base-${user.home}/.sbt}/boot/}
lock: false
[ivy]
ivy-home: ${sbt.ivy.home-${user.home}/.ivy2/}
checksums: ${sbt.checksums-sha1,md5}
override-build-repos: ${sbt.override.build.repos-false}
repository-config: ${sbt.repository.config-${sbt.global.base-${user.home}/.sbt}/repositories}
Another point of attention is also what they said on that google group. Do not run two sbt processes at the same time, as this parameter might cause inconsistencies then.
