Maven doesnt use specified source and target settings - java

I'm trying to build a java project using maven. In the pom.xml file at the root of the project I have the following lines:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.6</source>
<target>1.6</target>
<debug>true</debug>
<encoding>UTF-8</encoding>
</configuration>
</plugin>
but when I try to build with mvn -DskipTests -U install, I get the following error: static import declarations are not supported in -source 1.3
maven is not using the source and target (1.6) that i've specified in the pom.
java -version
java version "1.7.0_11"
Java(TM) SE Runtime Environment (build 1.7.0_11-b21)
Java HotSpot(TM) 64-Bit Server VM (build 23.6-b04, mixed mode)
mvn --version

Is there anywhere else that maven might be getting its default source and target settings from? Why isnt it using the settings from the pom?
Here is a snippet of error message when maven is ran in debug mode:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.0.2:compile (default-compile) on project LeaderLines: Compilation failure
[ERROR] /path/geoserver-2.2/geotools-plugin/LeaderLines/src/org/geotools/filter/function/FilterFunction_leaderLine.java:[22,7] error: static import declarations are not supported in -source 1.3

Try setting the source level and source encoding with the following properties:
<properties>
<maven.compiler.source>1.6</maven.compiler.source>
<maven.compiler.target>1.6</maven.compiler.target>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>

Try to clear you local Maven repo and run your build again (maybe, try also to run it with '-o' option)

Please help me to resolve the issue.
Your error says
Fatal error compiling: error: invalid target release: 13.0.1
You are using maven-compiler-plugin 3.0 however you need at least 3.8 to work with Java 13. This can be done with <plugin> tag, although you probably should consider updating Maven to 3.5:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.8.0</version>
<configuration>
<source>13</source>
<target>13</target>
</configuration>
</plugin>
Take a look at this article to see what else is needed to work with Java 13.

Why does Maven use the wrong JDK version when running from Fish?

I run macOS Sierra, and have installed the Fish shell (https://fishshell.com/).
When I try to build a Maven project, it now gives me
Fatal error compiling: invalid target release: 1.8 ->
... which means that it has picked up an older JDK which it tries to use to build my Java 8 project with.
This is made obvious by running mvn -version:
...
Java version: 1.6.0_65, vendor: Apple Inc.
Java home: /Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home
...
But I have JAVA_HOME set correctly, echo $JAVA_HOME in both shells give me:
/Library/Java/JavaVirtualMachines/jdk1.8.0_112.jdk/Contents/Home
and java -version gives me
java version "1.8.0_112"
Java(TM) SE Runtime Environment (build 1.8.0_112-b16)
and javac -version:
javac 1.8.0_112
echo $PATHgives the same result in both shells (except that in Bash, the directories are separated by :; in Fish, a space ):
/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Applications/Server.app/Contents/ServerRoot/usr/bin:/Applications/Server.app/Contents/ServerRoot/usr/sbin
I have configured maven-compiler-plugin to for 1.8:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.6.0</version>
<configuration>
<source>1.8</source>
<target>1.8</target>
<encoding>${project.build.sourceEncoding}</encoding>
</configuration>
</plugin>
Why does Maven insist on using the 1.6 JDK? The same project builds fine, with the correct 1.8 JDK, when running through Bash.
If you are running an old version of maven, please try updating to the latest version (3.5.0), e.g. via homebrew (brew install maven).

javac: invalid target release: 1.8 on Mac when executing Maven command

I am trying to run automation test on Mac. I installed Maven and java, jdk as following:
java version "1.8.0_25"
Java(TM) SE Runtime Environment (build 1.8.0_25-b17)
Java HotSpot(TM) 64-Bit Server VM (build 25.25-b02, mixed mode)
and Maven:
Apache Maven 3.2.5 (12a6b3acb947671f09b81f49094c53f426d8cea1; 2014-12-14T18:29:23+01:00)
Maven home: /usr/local/Cellar/maven/3.2.5/libexec
Java version: 1.6.0_65, vendor: Apple Inc.
Java home: /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home
Default locale: en_US, platform encoding: MacRoman
OS name: "mac os x", version: "10.9.5", arch: "x86_64", family: "mac"
When I executed Maven command, I got this error:
[ERROR] Failure executing javac, but could not parse the error:
[ERROR] javac: invalid target release: 1.8
[ERROR] Usage: javac <options> <source files>
[ERROR] use -help for a list of possible options
[ERROR] -> [Help 1]
I searched on here, there's one accepted solution is this:
sudo cp $JAVA_HOME/lib/tools.jar /Library/Java/Extensions/
I executed this command, but nothing happened! I don't know what's wrong.
First, figure out where 1.8 Java is installed by running the command:
/usr/libexec/java_home -v 1.8
Then, set your JAVA_HOME environment variable by running the command:
export JAVA_HOME=<whatever the output from the previous command was>
Maven should work afterwards, at least in that terminal window.
You'll have to set the JAVA_HOME environment variable in your profile if you don't want to have to run these commands every time you open a new terminal.
If you haven't done so already, use the maven-compiler-plugin to determine the Java version to use within Maven. Put this in your pom.xml file (change the <source/> and <target/> version to the JDK version you require):
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.1</version>
<configuration>
<source>1.8</source>
<target>1.8</target>
</configuration>
</plugin>
</plugins>
</build>
(If you already have a <build/> and/or <plugins/> section, add the <plugin/> portion, only.)

Any help would be appreciated.
The problem is that your maven is using java 5 (as your comment says). You have to change your JAVA_HOME variable to point to jdk 6 or higher. Look at :
Error when using javac: "javac: invalid flag: -s"
In my case i dont have the apropiate environment variable because the project is inherited, and I had not created the variable JDK_WAS85_JDK8 = C:\Program Files\Java\jdk1.8.0_221.
Usually is JAVA_HOME the variable that is set.
