[SOLVED] Why does Eclipse Kepler SR1 error with : JAX-RS 2.0 requires Java 1.7 or newer

Why does Eclipse Kepler SR1 error with : JAX-RS 2.0 requires Java 1.7 or newer

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.fake.company</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?

Solution

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.
