Description:
Field taskLauncher in org.springframework.cloud.task.launcher.TaskLauncherSink required a bean of type 'org.springframework.cloud.deployer.spi.task.TaskLauncher' that could not be found.

Action:
Consider defining a bean of type 'org.springframework.cloud.deployer.spi.task.TaskLauncher' in your configuration.

Answer 1

我刚刚遇到了同样的问题，我通过任务启动器本地示例解决了它。我需要做的是将部署程序本地依赖项添加到我的 pom 文件中。

特别是，添加以下句子解决了该问题：

<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-deployer-local</artifactId>
<version>1.3.7.RELEASE</version>
<exclusions>
<exclusion>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
</exclusion>
</exclusions>
</dependency>
