ive imported a bunch on maven projects from svn and they all (...a lot) try to use 

JRE System Library [JavaSE-1.7]

But i only have 

jdk1.8.0_102_64Bit

Which i told eclipse about in eclipse.ini with:

-vm C:\Users\myuser\Downloads\jdk1.8.0_102_64Bit\bin

Yet all the imported maven projects insist to use the "System JRE" which is unbound when i check it.

How do you tell maven to use what eclipse knows about? or where does maven get its information about JDK's / JRE'S?

  • I guess thy will be use the Compiler plugin.There can you set the target Version of the Project. – Jens Aug 28 '17 at 08:13

Maven by default uses JAVA_HOME Environment Variable to know which java version to use. Unless you set different one in pom.xml.

Try check every pom.xml of your projects, they must have a plugin section like this:

<plugin>
     <groupId>org.apache.maven.plugins</groupId>
     <artifactId>maven-compiler-plugin</artifactId>
     <version>3.1</version>
     <configuration>
         <verbose>true</verbose>
         <fork>true</fork>
         <executable>${JAVA_1_6_HOME}/bin/javac</executable>
     </configuration>
</plugin>

Executable tag tell maven to use java 6 in this example.

In this case i probably did something wrong while importing it from svn..a second try worked, but im not sure why :(
