Scala 2.10 with JDK9 compilation error

[vveider]

Hi, Scala dev team!

I'm trying to compile Apache Ignite #master under JDK9 and one of it's modules (ignite-scalar_2.10) is categorically refuses to do so.

I run
mvn install -U -Pall-java,all-scala,licenses,lgpl,examples -DskipTests -Dmaven.javadoc.skip=true -pl :ignite-scalar_2.10 -am

and have the following problems:

Scala version is 2.10.7

Can you please advise some workaround or alike?


Thanks!

[SethTisue]

looks like a duplicate of #10603, if I'm wrong lmk

[SethTisue]

note that in general Scala 2.10 is only just baaaarely supported on JDK 9+, and even that minimal support primarily exists for users who are still upgrading from sbt 0.13 (which needs 2.10) to sbt 1. so just be aware that this may not be the only problem you hit.

most Scala library authors are no longer publishing new versions for 2.10.

@SethTisue, if it is duplicate, then can you advise how should I set scala compiler options from maven?

[martin-g]

@vveider Does this example help you ?

[vveider]

@martin-g, thanks, that worked!
@SethTisue, FYI, -nc is unrecognized option, though -nobootcp is enough for successful compilation.
