Hi Uwe,
I further tried few points as per your
https://github.com/apache/lucene/pull/177/ and added javac.gradle file
changes,that solved my above problem but still it unables to recognize
any classes from jdk.incubator.vector package and throwing following errors.
What I added under javac.gradle
configure(project(":lucene:core")) {
plugins.withType(JavaPlugin) {
tasks.named('compileJava').configure {
sourceCompatibility = 17
targetCompatibility = 17
options.compilerArgs += ["--release", 17 as String, "--add-modules",
"jdk.incubator.vector"]
options.compilerArgs -= "-Werror"
}
}
}
Following is the error, I got during build
./gradlew assemble
> Task :lucene:core:renderSiteJavadoc
error: cannot find symbol
*private static final VectorSpecies<Long> SPECIES =
LongVector.SPECIES_PREFERRED;*
^
symbol: class VectorSpecies
error: package jdk.incubator.vector does not exist
*import jdk.incubator.vector.*;*
^
2 errors
Any help will be really appreciated.
Thanks & Regards,
Balmukund
