Cannot build with sbt
When I try to build with sbt I get:
Project loading failed: (r)etry, (q)uit, (l)ast, or (i)gnore? r error: error while loading CharSequence, class file '/usr/lib/jvm/java-8-oracle/jre/lib/rt.jar(java/lang/CharSequence.class)' is broken (bad constant pool tag 15 at byte 1484) [error] Type error in expression
Using Java 7 is not a very good option when Java is installed system-wide. I have this problem and it looks like the sbt launcher juses whatever java is in the PATH. I tried setting JAVA_HOME and JDK_HOME but it still takes the default Java.
This needs 2 levels of fix. Firstly, some way to tell the launcher to use an alternative JDK, secondly a patch to SBT so that it will run under Java 8.
Old scala 2.9x does not work with Java8 So the only way to make it work with JDK8 is to use Scala 2.10 and sbt 0.13 (as sbt 0.12 uses scala 2.9x internally).
Updating the system-wide default Java version for one application (sbt) is a bit of a drag. I ended up writing a script that pushes Java7 onto the front of my PATH before execing the real sbt script. Functional but eugh!
I had the same problem and changed my sbt launcher script to read
#!/bin/bash
test -f ~/.sbtconfig && . ~/.sbtconfig
exec $JAVACMD -Xmx1512M ${SBT_OPTS} -jar /usr/local/Cellar/sbt/0.13.0/libexec/sbt-launch.jar "$@"
Now I can use another Java version for sbt with
export JAVACMD=/Library/Java/JavaVirtualMachines/jdk1.7.0_45.jdk/Contents/Home/bin/java
sbt
Note that although the launcher explicitly mentions 0.13.0 the sbt-launch.jar should spawn the sbt version specified in build.properties.
I had the same problem in an entirely different context, when building jOOQ-scala with Maven and Java 8: https://travis-ci.org/jOOQ/jOOQ/jobs/23113386

I suspect that there is a Scala / Java 8 issue
/usr/libexec/java_home -v 1.7 gives the path to the JDK 1.7. You can change your sbt start script in the meantime:
cat /usr/local/bin/sbt
#!/bin/sh
test -f ~/.sbtconfig && . ~/.sbtconfig
exec /usr/libexec/java_home -v 1.7 --exec java -Xmx512M ${SBT_OPTS} -jar /usr/local/Cellar/sbt/0.13.2/libexec/sbt-launch.jar "$@"

@svanschalkwyk you're right, I had to fix it in my fork. I switch to a CDN → see https://github.com/andypetrella/spark-notebook/blob/spark/server/src/main/assets/thirdparty/static/less.jsm
Much appreciated! Getting "unauthorized" in web page. Will look some more.

If you want to use URL rather than the page opened by the app, you will have this error (security via cookie token not found). So =>
project server
run --disable_security
Will disable the security and let you use the app in DEV mode (let's say), thus reloading page at will.

Thanks!

Thanks Andy. Much appreciated! How can I do the same as I'm doing here: KERNEL_CMD="["java", "-cp", "${ALL_LIBS}", "$JAVA_NATIVE", "${MEMSIZE}", "-Xms128M", "-Dfile.encoding=UTF-8", "org.refptr.iscala.IScala", "--profile", "{connection_file}", "--parent", "$@"]"
ipython notebook --profile scala
--KernelManager.kernel_cmd="$KERNEL_CMD" Regards Steph PS. I'm new to Linux, new to Scala, new to the entire dark side. Been doing MSFT since 92...

@svanschalkwyk actually, I dunno, this command look quite weird to me :-D. I'm using the notebook tru sbt only. In a sense, this command looks pretty like a classical IPython one no?
Hi Yes, it does look weird The kernel keeps on stopping, so something is wrong. S

I have sbt 0.13 and jdk 1.8 . it is compiling on scalac 2.10 but I have the same error "java.io.FileNotFoundException: https://raw.githubusercontent.com/cloudhead/less.js/master/dist/less-1.3.3.js"
