Documentation (wrongly?) says Maven 3.3.1 runs with Java 1.6
Hi,
Maven 3.3.1 requires Java 1.7:
- [MNG-5780] - upgrade Java minimum version prerequisite from Java 6 to
Java 7
- When I try to run Maven 3.3.1 with Java 1.6 I get the exception:
Exception in thread "main" java.lang.UnsupportedClassVersionError:
org/apache/maven/cli/MavenCli : Unsupported major.minor version 51.0
But the documentation says the system requirements are still at Java 1.6:
- On the download page: http://maven.apache.org/download.cgi#Requirements
- In README.txt when downloading Maven 3.3.1:
System Requirements
-------------------
JDK:
1.6 or above (this is to execute Maven - it still allows you to build
against 1.3
and prior JDK's).
I assume the requirement is really Java 1.7 but the documentation has not
been updated?
Regards,
Arend

Hi,
I tested 3.3 a little bit and didn't find any issue
But it requires Java 7 if you need to build with an older version of Java
you'll have to setup a toolchain
You can always find old releases from :
http://archive.apache.org/dist/maven/maven-3/
http://archive.apache.org/dist/maven/binaries/

Hi group,
I have the same problem. Looking for the 3.2.x releases. Can’t upgrade to 3.3.x yet.
Or is it save to skip 3.2.x for now?

Re: Documentation (wrongly?) says Maven 3.3.1 runs with Java 1.6
Posted by Arnaud Héritier <ah...@gmail.com>.
I'm a little bit lost with the download page
Several time it references Maven 3.2 but this one isn't available any more
(only in archives)
But 3.2 is the one to use for Java 6 users ? (If we exclude the usage of
toolschain)
I'm not sure why we are keeping 3.0, 3.1 and not 3.2

ok, thanks for the clarification.
The system requirements on the download page are correct now.
But the README.txt in the distribution is still wrong.
