Could not exec java with Spring+Maven exit code 1
提问by NiHao92
I am new to Spring/Maven, and am following this tutorial: Serving Web Content with Spring MVC.
我是 Spring/Maven 的新手，正在学习本教程： 使用 Spring MVC 服务 Web 内容。
Everytime I run mvn spring-boot:run, I get this error:
每次运行时mvn spring-boot:run，都会出现此错误：
Failed to execute goal org.springframework.boot:spring-boot-maven-plugin:1.5.2.RELEASE:run (default-cli) on project gs-serving-web-content: Could not exec java: Application finished with exit code: 1 ->
Failed to execute goal org.springframework.boot:spring-boot-maven-plugin:1.5.2.RELEASE:run (default-cli) on project gs-serving-web-content: Could not exec java: Application finished with exit code: 1 ->
I tried to add classpath, tried to run mvn install clean spring-boot:run, did a lot of other things that people suggested on stackoverflow in similar situations, spent on this more than 8 hours - no use.
我尝试添加类路径，尝试运行mvn install clean spring-boot:run，做了很多其他人在类似情况下在 stackoverflow 上建议的事情，在这上面花费了 8 个多小时 - 没有用。
Here is my main class Application.java:
这是我的主要课程Application.java：
package hello;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class Application {
public static void main(String[] args) throws Exception{
SpringApplication.run(Application.class, args);
}
}

@Controller
public class GreetingController {
@RequestMapping("/greeting")
public String greeting(@RequestParam(value="name", required=false, defaultValue="World") String name, Model model) {
model.addAttribute("name", name);

I made the following changes to make mvn clean spring-boot:runwork:
我进行了以下更改以使其mvn clean spring-boot:run工作：
- Move
pom.xmlto the root directory, which makes the directory hierarchy to be:
- 移动
pom.xml到根目录，这使得目录层次结构为：

目录层次结构：

It seems you meant to exclude those dependencies. mvn clean spring-boot:runwill just exit successfully if the embed tomcat is excluded, but I think this is the correct behave because there's no container to deploy the application. Anyway, you can try it out and make changes according your requirements.
您似乎打算排除这些依赖项。mvn clean spring-boot:run如果嵌入的 tomcat 被排除，它将成功退出，但我认为这是正确的行为，因为没有容器来部署应用程序。无论如何，您可以尝试一下并根据您的要求进行更改。

Sometimes the port might just be already in use, make sure you kill all java processes before running an application.
有时端口可能已经在使用中，请确保在运行应用程序之前终止所有 Java 进程。

I've same error as yours and finally I found it was cased by the wrong cooperation version between "spring-boot-starter-parent" and "spring-boot-autoconfigure", thereof making sure with same version. And also check their versions are the newest nor not.
我和你的错误一样，最后我发现它是由“spring-boot-starter-parent”和“spring-boot-autoconfigure”之间的错误合作版本造成的，确保使用相同的版本。还要检查他们的版本是不是最新的。
<parent>

<artifactId>spring-boot-starter-parent</artifactId>

In my case I just delete "devtools" dependency.
就我而言，我只是删除了“devtools”依赖项。
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-devtools</artifactId>
<optional>true</optional>
</dependency>
And it works!
它有效！
