Subject [jira] [Updated] (SPARK-26813) Consolidate java version across language compilers and build tools
Date Sat, 02 Feb 2019 05:48:00 GMT

     [ https://issues.apache.org/jira/browse/SPARK-26813?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Chenxiao Mao updated SPARK-26813:
---------------------------------
    Description: 
The java version here means versions of javac source, javac target, scalac target. They could
be consolidated as a single version (currently 1.8)
|| ||javac||scalac||
|source|1.8|2.12/2.11|
|target|1.8|1.8|

The current issues are as follows
 * Maven defines a single property to specify java version (java.version) while SBT build
defines different properties for javac (javacJVMVersion) and scalac (scalacJVMVersion). SBT
should use a single property as Maven does.
 * Furthermore, it's even better for SBT to refer to java.version defined by Maven. This is
possible since we've already been using sbt-pom-reader.
