checkstyle plugin throwing major.minor 52 error on maven package, development env problem

I believe this is an issue with my development environment since I was able to build this jar before I needed switch to a new laptop.
I need to build this jar with java version 1.7 due to production environment requirements.
In the pom.xml I have the properties
<properties>
<checkstyle.version>8.10.1</checkstyle.version>
<maven.compiler.source>1.7</maven.compiler.source>
<maven.compiler.target>1.7</maven.compiler.target>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>

When I run:

It fails with the output:

Changing my JAVA_HOME to java 1.8 allows it to build properly, but I need it to be built in 1.7 for the environment it runs in.

Usually, it is no problem to build with JDK 1.8 for Java 1.7. The resulting artifacts will run on a Java 1.7 environment just fine.
If you don't want this, you need to downgrade your checkstyle plugin to a version that still support Java 1.7.

Environment variables returning blank even though Maven build is happening fine

I'm using Maven as a build tool for Scala code. I'm able to build the Scala objects fine using maven. However when I echo $M2_HOME ,$M2,$JAVA_HOME, everything is returning blank. While this is a sign that these environment variables are not set properly, they are not causing any issues, which to me sounded a bit surprising. Can you please let me know what I'm missing here. I'm running Ubuntu 15.04 and included the below output if needed.
~$java -version

This is the first time I'm using Java, Maven and Scala so kindly excuse my ignorance.

Maven compilation Error creating artifacts and copying them into the local repository

I have this compilation error un maven
[ERROR] COMPILATION ERROR :

But It's not possible because I have the jdk in my path: ;..;C:\PROGRA~2\Java\jdk1.7.0_71\bin

Maven in OSX Keeps Compiling with Java 1.5

I have a code that I'm working on from 2 different location, a Win7 machine and an OSX.
When worked on using Win7 machine, I don't need to bother about which java version that Maven compiles, I just need to set the PATH variable. If I'm on Java 5, it compiles against Java 5, if I'm on Java 7, it compiles against Java 7. No problem there.
Different case for my OSX machine. Now this is the exact same set of codes.
My Java version
[Mac-Pro] ~/apache-maven/apache-maven-3.1.1/conf $
p01ntbl4nk> java -version
java version "1.7.0_60"
Java(TM) SE Runtime Environment (build 1.7.0_60-b19)
Java HotSpot(TM) 64-Bit Server VM (build 24.60-b09, mixed mode)
My Maven version
[Mac-Pro] ~/apache-maven/apache-maven-3.1.1/conf $
p01ntbl4nk> mvn -version
Apache Maven 3.1.1 (0728685237757ffbf44136acec0402957f723d9a; 2013-09-17 23:22:22+0800)
Maven home: /Users/p01ntbl4nk/apache-maven/apache-maven-default
Java version: 1.7.0_60, vendor: Oracle Corporation
Java home: /Library/Java/JavaVirtualMachines/jdk1.7.0_60.jdk/Contents/Home/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "mac os x", version: "10.9.1", arch: "x86_64", family: "mac"
Both shows the same java version. Java 7u60.
But when I run mvn clean compile on my codes, I am getting this "try-with-resource is not supported in -source1.5"
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.5.1:compile (default-compile) on project archival-client: Compilation failure
[ERROR] /Users/p01ntbl4nk/GitRepositories/GenericArchival/root/archival-client/src/main/java/org/si/genericArchival/client/App.java:[140,6] error: try-with-resources is not supported in -source 1.5
[ERROR] -> [Help 1]
[ERROR]
I've checked, I don't have any reference in my main maven settings.xml or in any of the pom.xml in the modules that would indicate to use sourve version 1.5
To fix this, I would have to add the following to all my pom.xml
<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.1</version>
<configuration>
<source>1.7</source>
<target>1.7</target>
</configuration>
</plugin>
But this would mean that the maven modules are no longer adaptable to the java version of the underlying platform.
Am I missing anything?

Well, you already have your answer, but here it is definitively.
http://maven.apache.org/plugins/maven-compiler-plugin/
Also note that at present the default source setting is 1.5 and the
default target setting is 1.5, independently of the JDK you run Maven
with. If you want to change these defaults, you should set source and
target as described in Setting the -source and -target of the Java
Compiler.

Cannot access DisposableBean and cannot access InitialzingBean

I'm trying to compile the oVirt open source project on fedora core 21,
java -version

On fedora core18 it works -

The spring that is being used is aligned to 3.1.1.RELEASE from what I can see
In both the machines.
Can you give a hand? I know I'm using code that implements InitialzingBean and DisposableBean, but still - if same spring version, how come it does not compile

we had this problem and we had installed JDK 1.8. When we installed JDK 1.7 then this issue disappeared. Try it, maybe it is your case :)
