java.lang.AbstractMethodError: org.slf4j.impl.Log4jLoggerAdapter.log(ava/lang/Object;Ljava/lang/Throwable;)V

Question

Я пытаюсь сделать samll Camel Application, но приходит ошибка, связанная с log4j. Я проверил на многих форумах, но, к сожалению, бесполезно. Пожалуйста, помогите мне решить эту проблему. Спасибо заранее.

зависимости gradle:

+--- org.slf4j:slf4j-api:1.7.6
|    |    \--- org.slf4j:jcl-over-slf4j:1.7.6
|    |         \--- org.slf4j:slf4j-api:1.7.6

log4j связанные зависимости:

    compile group: 'org.slf4j', name: 'jcl-over-slf4j', version:'1.5.8'
    compile group: 'org.slf4j', name: 'slf4j-api', version:'1.5.8'
    compile group: 'org.slf4j', name: 'slf4j-log4j12', version:'1.5.8'
    compile group: 'log4j', name: 'log4j', version:'1.2.14'

Answer 1

Для работы, версия API SLF4J и его версия привязки должны быть совместимы (в общем, та же версия).

Во время выполнения используется привязка SLF4J 1.5.8, но загружен API SLF4J версии 1.6/1.7:

SLF4J: Запрошенная версия 1.5.8 вашей привязкой slf4j не совместима с [1.6, 1.7]

Вероятно, у вас есть транзитивная зависимость, которая использует версию 1.6/1.7 API SLF4J.
Вы также можете указать этот jar в classpath, используемом во время выполнения. Проверьте оба.

Чтобы проверить зависимости вашего проекта Gradle, вы можете использовать gradle app:dependencies получить дерево зависимостей вашего gradle-проекта.
