Perhaps a version of maven war plugin is being used, which does not work with Java 7? As per this issue (which describes a similar problem), 2.1.1 version of maven war plugin should work.

Include the following in your pom.xml 

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-war-plugin</artifactId>
    <version>2.1.1</version>
</plugin>

I had this problem when doing a mvn install. I resolved it by doing a mvn clean first, followed by a mvn install.

Using maven 2.1.1, JDK 1.7.0.45.

It's confirmed: JDK7 with Maven 2.x will produce this error.

I am using Maven 2.2.1 and JDK7 and got this error. I changed the JDK to version 1.6 and it's working fine.

Instead of changing JDK versions and Maven versions, try this:

<plugin>
    <artifactId>maven-compiler-plugin</artifactId>
    <configuration>
        <source>1.7</source>
        <target>1.7</target>
    </configuration>
    <version>2.3.2</version>
</plugin>

Confirmed, I ran into the same issue with maven 3.0.2 and jdk 1.7.0_02. After running against jdk 1.6.0_30 it compiled just fine.

I don't think the version was the problem. I solved deleting my target folder (because it contains webapp-cache.xml) and doing Maven install again.

Apache Maven WAR Plugin 3.0.0 resolved all issues:

<artifactId>maven-war-plugin</artifactId>
<version>3.0.0</version>

It doesn't matter if you use jdk 1.6, 1.7 or 1.8

This definitely seems to be related to incompatible plugin, library and language versions.

Two years, and two Java versions later, I had this same error while doing a sample project from an older book on Spring and Hibernate.

I was able to resolve the error by commenting out all of the version tags for the apache.maven.plugins and setting the Java version to 1.8. This let me know what was the latest and greatest version of the libraries, with the cost of some warnings from Maven about missing the version tags. If you care about the warnings, you can set the version tags to be latest version and the warnings from Maven should go away.

I executed mvn clean package and then just mvn package.

<plugin>
     <groupId>org.apache.maven.plugins</groupId>
     <artifactId>maven-war-plugin</artifactId>
<!-- <version>2.1-beta-1</version> -->
</plugin>
<plugin>
     <groupId>org.apache.maven.plugins</groupId>
     <artifactId>maven-compiler-plugin</artifactId>
<!-- <version>2.1</version> -->
     <configuration>
          <source>1.8</source>
          <target>1.8</target>
     </configuration>
</plugin>

if your using jdk 1.6 kindly add this plugin entry to your pom.xml

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>2.0.2</version>
    <configuration>
        <source>1.6</source>
        <target>1.6</target>
        <compilerArgument>-Xlint:all</compilerArgument>
        <showWarnings>true</showWarnings>
        <showDeprecation>true</showDeprecation>
    </configuration>
</plugin>

I had this problem with my eclipse Kepler. As soon as I moved to 4.4 (Luna) , all gone. Must be an issue with eclipse + maven embedded

I tried both JDK 1.7 and 1.8. No difference.

For me changing plugin version could not solve problme and changing JDK version is not in my control.

However running mvn clean before mvn tomcat6:deploy solved this problem.
