Answer 1

This helped me:

1. Right Click on Project.
2. Click on Build path.
3. Click on Configure Build path.
4. It opens a Java Build path window.
5. Click on Java Compiler in the Left side.
6. It navigates to Java Compiler window in that to set the Compiler compliance level is set as according to your jre version(ex if java version is 1.8 then choose 1.8) as select.
7. Click on [Apply] button.
8. Click on [OK] button.
9. Right click on Project > Maven > Update the project.
10. Right click on Project > Run As > Maven install -- The pom.xml file is running and java jars are download and installed to project.
11. Right click on Project > Run As > Maven Test -- The pom.xml file is running and java jars are download and installed to project.

Then you got the Build Success message and your maven project is created successfully.

What helped me was these lines in pom.xml file

<properties>
     <maven.compiler.source>1.8</maven.compiler.source>
     <maven.compiler.target>1.8</maven.compiler.target>
</properties>

Answer 3

I was facing the same issue and resolved it with the lines of code below:

<properties>
   <maven.compiler.source>1.6</maven.compiler.source>
   <maven.compiler.target>1.6</maven.compiler.target>
 </properties>

Answer 4

On MacOS I have multiple versions

user> ls /Library/Java/JavaVirtualMachines/
jdk-11.0.4.jdk      jdk-12.0.2.jdk      jdk1.8.0_221.jdk

and JAVA_HOME was not defined properly so Maven used jdk-12. I have jdk-11,jdk-8, and jdk-12.

user> mvn -version
Apache Maven 3.6.1 
Maven home: /usr/local/Cellar/maven/3.6.1/libexec
Java version: 12.0.2, vendor: Oracle Corporation, runtime: /Library/Java/JavaVirtualMachines/jdk-12.0.2.jdk/Contents/Home
Default locale: XXX, platform encoding: UTF-8
OS name: "mac os x", version: "10.14.6", arch: "x86_64", family: "mac"

So:

Define JAVA_HOME to use jdk-8.

export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_221.jdk/Contents/Home

Try again, now maven is:

user> mvn -version
    Maven home: /usr/local/Cellar/maven/3.6.1/libexec
    Java version: 1.8.0_221, vendor: Oracle Corporation, runtime: /Library/Java/JavaVirtualMachines/jdk1.8.0_221.jdk/Contents/Home/jre

and the build is:

[INFO] BUILD SUCCESS
