Maven Compile Error
Solution 1
The problem is that maven-compiler-plugin
in Maven2 by default uses -source 1.3
and target 1.3
You can fix it by adding this to your pom:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<compilerVersion>1.5</compilerVersion>
<source>1.5</source>
<target>1.5</target>
</configuration>
</plugin>
It's practical to put this into pluginManagement
section in your topmost parent pom so that your derived poms do not need to care about this.
Solution 2
You have to add some informations in your pom.xml. Something like that:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>2.3.2</version>
<configuration>
<source>1.6</source>
<target>1.6</target>
</configuration>
</plugin>
Solution 3
In your log, I see this line:
generics are not supported in -source 1.3
Check the source and target configuration of maven-compiler plug-in, and update it to 1.5.

When I build and run my program in Netbeans, it works without a problem. But with same pom.xml file when I try "mvn compile" I get this error:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.0.2:compile (default-compile) on project hadoop-test: Compilation failure [ERROR] /home/metin/NetBeansProjects/hadoop-test/src/main/java/com/citusdata/hadoop/HadoopTest.java:[53,8] error: generics are not supported in -source 1.3
My java version is not 1.3, here the result of "mvn -version"
Apache Maven 3.0.4 Maven home: /usr/share/maven Java version: 1.7.0_03, vendor: Oracle Corporation Java home: /usr/lib/jvm/java-7-openjdk-amd64/jre Default locale: en_US, platform encoding: UTF-8 OS name: "linux", version: "3.2.0-27-generic", arch: "amd64", family: "unix"
and this is the line 53:
Token<BlockTokenIdentifier> token = locatedBlock.getBlockToken();
