如何使用.war文件将我的wildfly 21 Rest API部署到heroku

Question

I have created a Dynamic Web Project on eclipse building a Rest API with wildfly on eclipse using Maven that perfectly runs locally, but I am experiencing some issues while trying to deploy my project on Heroku.

我已经检查了 heroku deploy:war 并且它在部署时工作但给出了一条奇怪的错误消息，指出 heroku 在尝试删除临时文件时发现问题，因为它正在被另一个进程使用。

错误：

heroku war:deploy  C:/Users/jorge/Desktop/RestApi/RestApi/target/RestApi-0.0.1-SNAPSHOT.war --app abyss-layers

这是我的 pom.xml 文件的样子：

还有我的 web.xml 文件：

    <welcome-file>default.htm</welcome-file>
    <welcome-file>default.jsp</welcome-file>
  </welcome-file-list>
 
</web-app>

我还找到了一些尝试使用 webapp 运行器部署的信息，但它基于 tomcat，并且还使用了如下插件：

 <plugin>
        <groupId>com.heroku.sdk</groupId>
        <artifactId>heroku-maven-plugin</artifactId>
        <version>3.0.3</version>
      </plugin>

and after setting the app name in the pom.xml, and executing mvn clean heroku:deploy-war -e -X as it is stated on https://devcenter.heroku.com/articles/deploying-java-applications-with- the-heroku-maven-plugin它给出了这个错误：

提前感谢任何可以给我帮助的人！

Answer 1

heroku war:deploy在 Heroku 可以理解的 package 中创建一个包含您的项目的临时文件。 这发生在您的本地计算机上。 它尝试通过删除这些临时文件来清理它们。

我不知道哪个进程可能使用此文件导致错误，但正如您所注意到的，这不会影响部署到 Heroku 本身。

您的heroku-maven-plugin的 output 很有趣。 失败的不是 Heroku 插件，而是 Maven 自己的clean插件。 您可以尝试运行mvn heroku:deploy-war看看是否有效吗？

无论如何，我为此记录了一个错误，并且当无法删除临时文件时，它会发出警告而不是崩溃。
