Build Failure "cannot find symbol"

Here is a transcript of the mvn install command run on my Mac.

Your JAVA_HOME probably points to a version of JDK below Java 8.

[drodenbaugh]

Well, that's only part of the story I think. I had a similar issue (I was running JDK 7 on my Mac) and when I added Java8 and recompiled, things were better, but still wrong (tests failed):

Daves-MacBook-Pro:wsdoc daver$ export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_40.jdk/Contents/Home/
Daves-MacBook-Pro:wsdoc daver$ set | grep JAVA
JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_40.jdk/Contents/Home/
_=JAVA_HOME
Daves-MacBook-Pro:wsdoc daver$ java -version
java version "1.8.0_40"
Java(TM) SE Runtime Environment (build 1.8.0_40-b27)
Java HotSpot(TM) 64-Bit Server VM (build 25.40-b25, mixed mode)

Running the build now yields a successful JAR creation, but failed tests:

Daves-MacBook-Pro:wsdoc daver$ mvn install

I found that changing this in the pom.xml fixed it for me:

From this:

            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <configuration>
                    <source>1.6</source>
                    <target>1.6</target>
                </configuration>
            </plugin>

To this

            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <configuration>
                    <source>1.8</source>
                    <target>1.8</target>
                </configuration>
            </plugin>

Make sure you do a mvn clean install after that change, or nothing will happen. I still see 14 tests failing now, but I did a -DskipTests=true and the JAR built and was running on my project anyhow. You should probably look into that. :)
