I have seen issues with some versions of the Scala Maven plugin auto-detecting the wrong JAVA_HOME when both a JRE and JDK are present on the system. Setting JAVA_HOME explicitly to a JDK skips the plugins auto-detect logic and avoids the problem.

Or you've actually installed the JRE. Only the JDK has javac, etc. On Mon, Apr 29, 2019 at 4:36 PM Shmuel Blitz <shmuel.bl...@similarweb.com> wrote: Hi, Trying to build Spark on Manjaro with OpenJDK version 1.8.0_212, and I'm getting the following error: Cannot run program "/usr/lib/jvm/java-8-openjdk/jre/bin/javac": error=2, No such file or directory > which javac /usr/bin/javac only when I set JAVA_HOME as follows, do I get it to run. > export JAVA_HOME=/usr/lib/jvm/default Any idea what the issue is? -- Shmuel Blitz Data Analysis Team Leader Email: shmuel.bl...@similarweb.com www.similarweb.com
