У меня проблема с запуском моего веб-приложения в gretty.Я использую следующую конфигурацию
gretty {
httpPort = 8080
servletContainer = 'tomcat9'
reloadOnClassChange = true
managedClassReload = true
loggingLevel = 'ALL'
springBootVersion = '2.1.1'
contextPath = '/iC'
interactiveMode = 'restartOnKeyPress'
jvmArgs = [
'-Xms512m',
'-Xmx2500m'
]
logDir = 'logs'
}
farm {
webapp "build/dist/${app_name}.war"
}
project.afterEvaluate {
tasks.farmRun.dependsOn build_war
}
При запуске я получаю следующие ошибки

Что странно, что я могу запустить веб-приложение в автономном экземпляре Tomcat (яУбедитесь, что версия tomcat и сервлет совпадают).
Плагин gretty отлично работает для другого моего веб-приложения, поэтому я предполагаю, что это проблема с самим веб-приложением, но я не знаю, гденачинайте находить корень проблемы, поскольку она работает в автономном экземпляре tomcat, что значительно усложняет эту задачу.
