在使用Maven构建项目时遇到问题

Question

I've just started work on a project that uses maven. However, when I try to build the project I get the following error:

MyClass.java:[7,2] annotations are not supported in -source 1.3
(use -source 5 or higher to enable annotations)
@Override

I have the latest JRE installed on my machine, and I have tried editing the pom.xml file to fix this but I have had no luck. I've also tried searching Google but I've come up with near nothing.

Does anyone know how I can configure the project to use the latest JRE? Or another solution if this isn't the problem.

Thanks in advance.

(Also, I have never used Maven before so forgive me if anything I say sounds stupid)

EDIT: I am using maven from the terminal in the latest Ubuntu release

Answer 1

Open your pom.xml and search for plug-in with artifact ID maven-compiler-plugin. Check tag . It seems it is 1.3 in your case. Change it to 1.5 (unless you really have to compile your code for JVM 1.3. In this case you should remove the stuff that is not compatible with this old version - eg annotations.)

Answer 2

I suspect that you have configured an older version of the JRE within your pom.xml.

Does your pom.xml contain something like this?

    <properties>
            <java.version>1.6</java.version>
    </properties>
    <build>
            <plugins>
                    <plugin>
                            <groupId>org.apache.maven.plugins</groupId>
                            <artifactId>maven-compiler-plugin</artifactId>
                            <configuration>
                                    <source>${java.version}</source>
                                    <target>${java.version}</target>
                            </configuration>
                    </plugin>
            </plugins>
    </build>
