打包完成后的 Spring Boot 程序如何部署到 Linux 上的服务？   你可以参考官方的有关部署 Spring Boot 为 Linux 服务的文档。 文档链接如下： https://docs.ossez.com/spring-boot-docs/docs/reference/html/deployment.html 请注意，在部署为 systemd 服务的时候，上面的配置文件为： [Unit] Description=myapp After=syslog.target [Service] User=myapp ExecStart=/var/myapp/myapp.jar SuccessExitStatus=143 [Install] WantedBy=multi-user.target 你需要自行修改 Description， user,  ExeStart 字段中的内容。 请注意，官方的配置可能不是非常正确。 假设我们的可执行 Jar 文件名为：reoc-mls-service-importer.jar 这个文件部署在：/home/reoc/reoc-mls-service-importer/reoc-mls-service-importer.jar 路径下。 如果你配置 ExecStart 为： ExecStart = /home/reoc/reoc-mls-service-importer/reoc-mls-service-importer.jar 你是没有办法运行的。 你需要配置为： ExecStart=/usr/bin/java -Xmx2048m -jar /home/reoc/reoc-mls-service-importer/reoc-mls-service-importer.jar 才可以。 其中 -Xmx2048m 是为这个进程指定分配的内存大小。 你也可以不分配内存，去掉这个参数也是可以的。

系统提示错误信息： Received status code 409 from server: Overwriting released artifacts is not allowed.   这是在 Archiva 默认的配置下如果你不是使用 snapshot 配置的话，是不允许对仓库进行重新部署的。 你可以手动修改 Archiva 的配置能够允许你对仓库进行重新部署，但是我们不建议你这样做。 对于非正式版的发布，你可以使用 snapshot。   配置的位置在你的 Archiva 仓库的配置中。

问题 在 Travis CI 编译的时候出现 Error: Could not find or load main class org.gradle.wrapper.GradleWrapperMain 错误。 详细的错误日志为： Error: Could not find or load main class org.gradle.wrapper.GradleWrapperMain The command "eval ./gradlew assemble " failed. Retrying, 2 of 3. Error: Could not find or load main class org.gradle.wrapper.GradleWrapperMain The command "eval ./gradlew assemble " failed. Retrying, 3 of 3.
