为什么Eclipse Kepler SR1错误：JAX-RS 2.0需要Java 1.7或更高版本 [英] Why does Eclipse Kepler SR1 error with : JAX-RS 2.0 requires Java 1.7 or newer

问题描述

我有一个maven项目提供以下两个错误

无法安装JAX-RS（REST Web服务）2.0：一个或多个约束还没有满足了。

JAX-RS（REST Web Services）2.0需要Java 1.7或更高版本。

我已经安装了JDK 1.6（我不能改变这个）

项目方面没有勾选JAX-RS。

项目facet具有java 1.6 set

项目方面有动态Web项目2.4集。

我有以下插件

Sonar 3.2.0
MercurialEclipse 2.10
EclEmma 2.2.1

pom.xml只是这个.. 。

 <？xml version =1.0encoding =UTF-8？> 
< project xmlns =http://maven.apache.org/POM/4.0.0xmlns：xsi =http://www.w3.org/2001/XMLSchema-instance
 xsi：schemaLocation =http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd\">

< groupId> com.pcmsgroup.v21.esi< / groupId> 
< artifactId> customerservice-war< / artifactId> 
< version> 2.0.0-SNAPSHOT< / version> 
< / project> 
  

web.xml是

 <？xml version =1.0encoding =UTF-8？> 
< web-app version =2.4xmlns =http://java.sun.com/xml/ns/j2ee
 xmlns：xsi =http：//www.w3。 org / 2001 / XMLSchema-instance

< display-name>客户服务< / display-name> 
< / web-app> 
  

清理或更新Maven项目没有任何区别。

注意：这是在eclipse-jee-kepler-SR1-win32-x86_64中。
注意：版本eclipse-jee-kepler-win32-x86_64没有给出错误。

注意：新工作区不会更改错误。 >

注意：我正在使用JDK.1.6.0_43

我可以看到的唯一错误与 .log文件是..

！ENTRY org.eclipse.osgi 2 1 2013-10-16 15：07：58.816
！MESSAGE NLS未使用的消息：JaxrsProjectConfigurator_The_project_does_not_contain_required_facets in：org.eclipse.m2e.wtp.jaxrs.internal.messages

添加方面，不要让我应用它，因为它说我需要Java 1.7

JSR339（ JSR339 ）声明API将广泛使用注释，并将
需要J2SE 6.0或更高版本

任何想法？

解决方案

删除 .project 并消除我从你的源代码控制。而不是使用导入 - >现有项目，请使用导入 - > Maven项目，并让m2e配置您的Eclipse项目。

I have a maven project that give the following two errors

JAX-RS (REST Web Services) 2.0 can not be installed : One or more constraints have not been satisfied.
JAX-RS (REST Web Services) 2.0 requires Java 1.7 or newer.

I have JDK 1.6 installed (I cant change this)

The project facets does NOT have JAX-RS ticked.

The project facets has java 1.6 set.

The project facets has Dynamic Web Project 2.4 set.

I have following plugins

Sonar 3.2.0 MercurialEclipse 2.10 EclEmma 2.2.1

The pom.xml is just this...

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <groupId>com.pcmsgroup.v21.esi</groupId>
    <artifactId>customerservice-war</artifactId>
    <version>2.0.0-SNAPSHOT</version>
</project>

the web.xml is

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
    <display-name>Customer Service</display-name>
</web-app>

Cleaning or "Update Maven Project" makes no difference.

Note: This is in eclipse-jee-kepler-SR1-win32-x86_64. Note: Version eclipse-jee-kepler-win32-x86_64 does not give the error.

Note: New workspace does not change the error.

Note: I'm using JDK.1.6.0_43

The only error I can see related to this in the ".log" file is..

!ENTRY org.eclipse.osgi 2 1 2013-10-16 15:07:58.816 !MESSAGE NLS unused message: JaxrsProjectConfigurator_The_project_does_not_contain_required_facets in: org.eclipse.m2e.wtp.jaxrs.internal.messages

Adding the facet, wont let me apply it since it says I need Java 1.7

JSR339 (JSR339) states "The API will make extensive use of annotations and will require J2SE 6.0 or later"

Any ideas?

解决方案

Delete the .project file and banish it from your source control. Instead of using Import -> Existing Project, use Import -> Maven project, and let m2e configure your Eclipse project.
