sbt 0.13.8 URI has an authority component

问题:

I get this error when running sbt in a sbt project. I have JDK 8 and sbt 0.13.8. I can run activator command without a problem but I need sbt working because my IDE (IntelliJ IDEA) uses it to load the project.

回答1:

The URI that activator adds to sbt repository list is lacking a third slash.

Open C:\Users\[USER]\.sbt\repositories

Add a third slash (i.e. activator-launcher-local: file:///${activator.local.repository-${activator.home-${user.home}/.activator}/repository}, [organization]/[module]/(scala_[scalaVersion]/)(sbt_[sbtVersion]/)[revision]/[type]s/artifact.[ext])

回答2:

I just removed the .sbt folder in C:\Users[USER]\ and the play project was imported successfully into intellij.

回答3:

The solution is a bit trickier (you need to re-insert the slash every time). See here: https://github.com/typesafehub/activator/issues/1037

回答4:

This is still an issue with Windows and the fix is to replace file:// with file:/// and doing so is super annoying so a good workaround is to setup a simple ant build.xml in the project root.

<project name="someName" default="run" basedir=".">
    <description>
        Fix sbt repositories
    </description>
    <property name="sbtrepo" location="${user.home}/.sbt/repositories"/>
    <target name="fixsbt">
        <replace file="${sbtrepo}" token="file://$" value="file:///$"/>
    </target>
    <target name="run" depends="fixsbt">
        <exec executable="C:\dev\Git\git-bash.exe" spawn="true">
            <arg line="-c 'activator run'" />
        </exec>
    </target>
</project>

You can either run the fixsbt target alone to do the file replace, or use the run target to fix the repositories file and then run activator. This example uses gitbash shell to run the command so you'll need to change the shell/path for your environment.
