作爲java應用程序顯示錯誤lanching spring-boot

Question

我無法在eclipse 3.9.0RELEASE中運行我的Spring Boot應用程序。 它如果提示啓動使用以下命令運行良好：

mvn spring-boot:run

但我更喜歡使用，而不是命令提示符我的春節，客戶端， 當我嘗試運行它，這樣做：運行AS-> Java應用程序或春天莽漢應用程序，然後我得到這個錯誤：

ERROR StatusLogger No log4j2 configuration file found. Using default configuration: logging only errors to the console. Exception in thread "main" java.lang.IllegalStateException: Failed to read Class-Path attribute from manifest of jar file:/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) at org.springframework.boot.devtools.restart.DefaultRestartInitializer.getUrls(DefaultRestartInitializer.java:91) at org.springframework.boot.devtools.restart.DefaultRestartInitializer.getInitialUrls(DefaultRestartInitializer.java:54) at org.springframework.boot.devtools.restart.Restarter.(Restarter.java:134) at org.springframework.boot.devtools.restart.Restarter.initialize(Restarter.java:531) at org.springframework.boot.devtools.restart.RestartApplicationListener.onApplicationStartedEvent(RestartApplicationListener.java:64) at org.springframework.boot.devtools.restart.RestartApplicationListener.onApplicationEvent(RestartApplicationListener.java:46) at org.springframework.context.event.SimpleApplicationEventMulticaster.invokeListener(SimpleApplicationEventMulticaster.java:166) at org.springframework.context.event.SimpleApplicationEventMulticaster.multicastEvent(SimpleApplicationEventMulticaster.java:138) at org.springframework.context.event.SimpleApplicationEventMulticaster.multicastEvent(SimpleApplicationEventMulticaster.java:121) at org.springframework.boot.context.event.EventPublishingRunListener.publishEvent(EventPublishingRunListener.java:111) at org.springframework.boot.context.event.EventPublishingRunListener.started(EventPublishingRunListener.java:60) at org.springframework.boot.SpringApplicationRunListeners.started(SpringApplicationRunListeners.java:48) at org.springframework.boot.SpringApplication.run(SpringApplication.java:302) at org.springframework.boot.SpringApplication.run(SpringApplication.java:1185) at org.springframework.boot.SpringApplication.run(SpringApplication.java:1174) at com.myshop.demo.Application.main(Application.java:26)

在我看來，該IDE不能成功地創建MANIFEST.MF文件（而不是Maven插件做完美的），但我不知道如何解決這個問題。

我也嘗試創建自己的文件粘貼在我的項目pah中：src/main/resources/META-INF/manifest.mf在jar中創建的一個，使用maven插件創建。

MANIFEST.MF：

Manifest-Version: 1.0 
Implementation-Title: demo 
Implementation-Version: 0.0.1-SNAPSHOT 
Archiver-Version: Plexus Archiver 
Built-By: MyFirstName MySecondName 
Start-Class: com.myshop.demo.Application 
Implementation-Vendor-Id: com.myshop 
Spring-Boot-Version: 1.3.6.RELEASE 
Created-By: Apache Maven 
Build-Jdk: 1.8.0_121 
Implementation-Vendor: Pivotal Software, Inc. 
Main-Class: org.springframework.boot.loader.JarLauncher 

但錯誤沒有改變。 謝謝你的幫助。

Answer 1

這是一個devtools啓動時的異常，請從pom.xml的是dependecy然後重新運行應用。
