显示错误将spring-boot作为java应用程序启动

Question

我无法在我的eclipse 3.9.0RELEASE中运行我的Spring Boot应用程序。如果使用以下命令在Prompt上启动它，它运行正常：

mvn spring-boot：运行

但我更喜欢使用我的Spring Client而不是命令提示符，当我尝试运行它时，执行：运行As-> Java Application或Spring Boor App，然后我收到此错误：

错误StatusLogger找不到log4j2配置文件。使用默认配置：仅将错误记录到控制台。线程“main”中的异常java.lang.IllegalStateException：无法从jar文件的清单中读取Class-Path属性：/ C：/Users/MyFirstName%20MySecondName/.m2/repository/org/codehaus/groovy/groovy/2.4。 7 / groovy-2.4.7.jar at org.springframework.boot.devtools.restart.ChangeableUrls.getUrlsFromClassPathOfJarManifestIfPossible（ChangeableUrls.java:100）at org.springframework.boot.devtools.restart.ChangeableUrls.fromUrlClassLoader（ChangeableUrls.java:88 ）org.springframework.boot.devtools.restart.DefaultRestartInitializer.getUrls（DefaultRestartInitializer.java:91）atg.springframework.boot.devtools.restart.DefaultRestartInitializer.getInitialUrls（DefaultRestartInitializer.java:54）at org.springframework.boot。 devtools.restart.Restarter。（Restarter.java:134）org.springframework.boot.devtools.restart.Restarter.initialize（Restarter.java:531）org.springframework.boot.devtools.restart.RestartApplicationListener.onApplicationStartedEvent（RestartApplicationListener） .java：64）在org.spring位于org.springframework.context.event.SimpleApplicationEventMulticaster.invokeListener（SimpleApplicationEventMulticaster.java:166）的framework.boot.devtools.restart.RestartApplicationListener.onApplicationEvent（RestartApplicationListener.java:46）org.springframework.context.event.SimpleApplicationEventMulticaster.multicastEvent（ SimpleApplicationEventMulticaster.java:138）org.springframework上的org.springframework.context.event.SimpleApplicationEventMulticaster.multicastEvent（SimpleApplicationEventMulticaster.java:121）org.springframework.boot.context.event.EventPublishingRunListener.publishEvent（EventPublishingRunListener.java:111） org.springframework.boot.SpringApplicationRunListeners.started（SpringApplicationRunListeners.java:48）中的.boot.context.event.EventPublishingRunListener.started（EventPublishingRunListener.java:60）org.springframework.boot.SpringApplication.run（SpringApplication.java:302） ）在org.springframework.boot.SpringApplication.run（SpringApplication.java:1185）at com.myshop.demo.Application.main上的org.springframework.boot.SpringApplication.run（SpringApplication.java:1174）（Application.java:26）

在我看来，IDE无法成功创建manifest.mf文件（而maven插件完美地完成它），但我不知道如何解决这个问题。

我还尝试在我的项目pah中创建自己粘贴的文件：src / main / resources / META-INF / manifest.mf在jar中找到的文件，使用maven插件创建。

MANIFEST.MF：

Manifest-Version: 1.0
Implementation-Title: demo
Implementation-Version: 0.0.1-SNAPSHOT
Archiver-Version: Plexus Archiver
Built-By: MyFirstName MySecondName

Created-By: Apache Maven
Build-Jdk: 1.8.0_121
Implementation-Vendor: Pivotal Software, Inc.

但错误没有改变。感谢您的任何帮助。

application.Java:

@SpringBootApplication
  public class Application {    
   public static void main(String[] args) {

    SpringApplication.run(Application.class, args);
  }
}

这是一个devtools启动异常，从pom.xml中删除该依赖项然后重新运行该应用程序。
