The following error is occurring
So I deleted the lib in elasticsearch/lib, but if I delete it, another error occurs
If I try to delete it from the java project, a code compilation error occurs, what should I do?
gradle code
```auto
buildscript {
ext {
publishedPluginVersion = rootProject.properties['pluginVersion']
pluginVersion = rootProject.properties['pluginVersion']
elasticsearchVersion = project.properties['elasticsearchVersion']
pluginName = rootProject.properties['pluginName']
luceneVersion = project.properties['luceneVersion']
javaVersion = 17
}
}
plugins {
id 'java'
}
apply plugin: 'java'
group 'org.elasticsearch.plugin'
compileJava.options.encoding = 'UTF-8'
repositories {
mavenCentral()
}
group = 'org.elasticsearch.plugin'
version = pluginVersion
