If you lot are edifice your Java projection using Maven, perhaps inwards Eclipse or from the ascendancy prompt past times running mvn install together with your construct is failing alongside an fault similar "invalid target release: 1.7" or "invalid target release: 1.8" together with then you lot receive got come upwardly to the right place. In this article, I'll demo you lot the argue why this fault occurs together with how you lot tin bargain alongside these errors fifty-fifty alongside higher Java version similar Java 9, 10 installed on your machine, or perhaps alongside Java eleven inwards the coming month. The root crusade of the occupation is that you lot receive got specified a higher Java version inwards your pom.xml file for Maven compiler plugin together with then what Maven knows inwards your system, together with that's why it's maxim invalid target release.
Influenza A virus subtype H5N1 uncomplicated solution to this occupation is either trim down your target version inwards pom.xml or install a novel Java version if you lot desire to construct your projection inwards higher version
But, the key to solving this occupation is knowing that Maven picks the Java version from the JAVA_HOME variable together with non from the PATH environs variable.
This agency fifty-fifty if you lot receive got JDK 8 installed but if your JAVA_HOME is yet referring to JDK 1.7 together with then you lot volition acquire this error.
Thankfully, you lot tin uncovering out that, I hateful which version of Java your Maven is using. Just run the mvn -version ascendancy from the ascendancy prompt together with it volition impress the value of JAVA_HOME variable together with confirm that which version of JDK it is using to construct your project.
Btw, if you lot are starting alongside Java together with Maven together with non familiar alongside telephone commutation concepts similar PATH, CLASSPATH, JAVA_HOME etc, I advise you lot to The Complete Java Masterclass to larn to a greater extent than those together with how Java plant inwards general, together with if you lot desire to larn Maven or but refresh the basic concepts, Maven Crash Course is a overnice course of teaching to showtime with.
Here is what my Maven pom.xml looks like:
Here is an illustration output of mvn -version:
$ mvn -version
Apache Maven 3.2.3 (33f8c3e1027c3ddde99d3cdebad2656a31e8fdf4; 2014-08-12T04:58:10+08:00

You tin regard that Maven inwards my machine was using JDK 1.6.0_37 together with that's why when I was edifice my Maven projection alongside JDK 1.7 equally the target it was failing.
Once I updated the pom.xml to utilisation target 1.6 the construct was started working.
Because Java vii was non required for my project, I but had to alter the Maven compile plugin equally follows:
But, if you lot receive got to construct your Java projection alongside JDK 1.7 together with then but install together with update your JAVA_HOME variable together with this fault volition become away.
This solution is actually overnice equally you lot tin solve the occupation immediately. Btw, if you lot desire to larn near Maven itself, I advise you lot receive got a await at the Spring, Maven, Ant, Gradle, together with other Java-related stuff.
You volition too receive got access to their interactive quizzes, exercises, together with latest certification material. To me, Pluarlsight is similar Netflix for Software Developers together with Since learning is an of import purpose of our job, Plurlasight membership is a swell way to remain ahead of your competition.
They too furnish a Windows and Linux.

Invalid target release: 1.7
Recently I was edifice a Java projection using Maven on my onetime machine when I encountered this error. I idea I receive got the latest Java version which I had together with that's why I surprised alongside this error.Here is what my Maven pom.xml looks like:

Btw, If you lot are working inwards the restricted environs similar in a big company where Software is deployed automatically together with can't add together or edit an environs variable, you lot tin yet alter them inwards the local musical rhythm out equally shown inwards my before article How to laid a specific Java version for Maven inwards Windows.
As explained inwards the previous department either alter the target into pom.xml or install a novel JDK together with updated the JAVA_HOME environs variable to indicate out novel JDK bin directory.
Since Maven uses JAVA_HOME, it volition non solve the occupation until you lot update this environs variable, fifty-fifty if you lot receive got installed the right version of Java.
Similarly, you lot volition acquire Invalid target release: 1.10 if you lot compile using <target>1.10</target> and your JAVA_HOME is referring to JDK nine or JDK 8.
Now you lot tin generalize this occupation together with solve depending upon which version of Java you lot receive got specified inwards your pom.xml together with which version of Java is installed on your machine together with referred past times the JAVA_HOME environs variable.
