Compilation failed

Hi,

While I follow steps from
https://gatling.io/docs/2.3/developing_gatling/building_gatling/

In the part where I have to run sbt compile on Gatling source code, I get this error:

overriding method getPrefixes in trait NamespaceContext of type (x$1: String)java.util.Iterator[String];
method getPrefixes has incompatible type
override def getPrefixes(uri: String): java.util.Iterator[_] = throw new UnsupportedOperationException
[error] ^
one error found
(gatling-core / Compile / compileIncremental) Compilation failed

sbt version 1.3.4
Scala version 2.12.10

Tnx!

Best,
Nevena Vasic

Are you really trying to build old dead Gatling 2.3???

Yes,
I have it cloned from here
https://github.com/gatling/gatling

2.3 branch has been dead for a very long time. Please switch to Gatling 3.2.1.

Again, the same - compilation failed.

You must use Java 8 to compile.

Latest problem,
after I run sbt publishLocal publishM2 in gatling-highcharts directory I get this error

(gatling-charts-highcharts-bundle / Universal / packageBin) java.io.IOException: Cannot run program “zip” (in directory “C:\Users\xxx\AppData\Local\Temp\sbt_72b0a6b6\gatling-charts-highcharts-bundle-3.3.0”): CreateProcess error=2, The system cannot find the file specified
