我有一个 Maven 项目，它给出以下两个错误

无法安装 JAX-RS（REST Web 服务）2.0：一个或多个约束没有得到满足。
JAX-RS（REST Web 服务）2.0 需要 Java 1.7 或更高版本。

我安装了 JDK 1.6（我无法更改）

项目方面没有勾选 JAX-RS。

项目方面有 java 1.6 集。

项目方面具有 Dynamic Web Project 2.4 集。

我有以下插件

声纳 3.2.0 MercurialEclipse 2.10 EclEmma 2.2.1

pom.xml 就是这样...

<?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.fake.company</groupId>
    <artifactId>customerservice-war</artifactId>
    <version>2.0.0-SNAPSHOT</version>
</project>

web.xml 是

<?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>

清理或“更新 Maven 项目”没有区别。

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

注意：新工作区不会更改错误。

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?

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.

It's a bug, fixed in Luna if not SR2. http://bugs.eclipse.org/416704

If the intention is to just get rid of these errors then you can simply right click on the errors in the "Marker View" and click delete.

I know you can't change your 1.6 JDK, but the following solution might help other people:

In my case, I have both JDK 1.6 and 1.7. I've tried several suggested solutions without any success.

Hence, in my pom.xml I changed from jdk 1.6 to jdk 1.7:

<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.0</version>
    <configuration>
        <source>1.7</source>
        <target>1.7</target>
    </configuration>
</plugin>

Using jdk 1.7 worked for me, although in my facets is setted the 1.6 (because my intention was use jdk 1.6).
