Maven Java EE Configuration

Question

In my maven project, I have this Effective POM:

In this moment, in the Markers tab on my Eclipse IDE, this error is being presented:

Description Resource    Path    Location    Type
Dynamic Web Module 3.0 requires Java 1.6 or newer.  example     line 1  Maven Java EE Configuration Problem
One or more constraints have not been satisfied.    example     line 1  Maven Java EE Configuration Problem

I try fix this configuration in the Build path from my project (In Properties/Java Build Path), but when I run Maven > Update Project, the value for this option returned to the previous one.

Where I should change this option to fix this error?

Answer 1

1. Go to project Build Path and change the Java Library version to 1.7
2. Go to Eclipse Preferences -> Java -> Compiler -> Change compliance level to 1.7
   
3. Right click on project -> Properties -> Project Facets
4. Uncheck Dynamic Web Module and click Apply (also uncheck JavaServer Faces if you had that)
5. Change the Java facet version to 1.7 and click Apply
6. Add the Dyanmic Web Module v3.0, apply.

Eclipse's facets configuration is buggy. Make sure you keep hitting Apply between checking and unchecking of facets.

Answer 2

GGrec's solution doesn't work for me. I manage to fixed this issue by adding to pom.xml this:

<build>
     <finalName>finalName</finalName>
     <plugins>

        <plugin>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.1</version>
            <configuration>
                <source>1.8</source> <!-- yours Java version -->
                <target>1.8</target> <!-- yours Java version -->
            </configuration>
        </plugin>

    </plugins>
</build>

UPDATE: In addition I figured out that everytime you run mvn install command on this pom.xml it overrides previous configuration. The right solution is either remove this version from pom.xml and set it up in eclipse options or just use configuration from pom.xml.

Answer 3

After following above troubleshooting steps. Update your maven project.

Right click on your project--> Maven--> Update Project

Or simply Alt+f5.

Hope this might help someone.

Answer 4

Also as Kefas I am specify java version to 1.7 and it works!

 <plugin>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.1</version>
    <configuration>
         <source>1.7</source> 
         <target>1.7</target> 
    </configuration>
</plugin>

Answer 5

The above suggests is helpful for me! Right click on project -> Properties -> Project Facets, then change the Java facets version to 1.7.

If it doesn't work, add the following code to pom.xml:

<build>
    <finalName>finalName</finalName>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.1</version>
            <configuration>
                <source>1.7</source> <!-- yours Java version -->
                <target>1.7</target> <!-- yours Java version -->
            </configuration>
        </plugin>
    </plugins>
</build>

Save pom.xml.

And then, right click on project-->Maven-->Update Project.
