Setting up a new jre to maven
Hi all,
I'm having problems setting up a new jre to run mvn install.
My default java version is 1.4.2_11, but I need maven to use jre 5 for it.
I've read the FAQ, but I must say the example for it is not really helpful.
Could somebody give me a hand on this sending a complete example?
thanks in advance
Allan Valeriano

Good day to you, Sha Jiang,
You may be running your maven2 in jdk1.5, but the plugins that uses java may
not necessarily use 1.5.
For example, you can set the maven-compiler-plugin (which by default,
handles the compile phase of your build) to a different JVM ( see [1] ) or
by specifying the source and targets ( see [2] ). Furthermore, you can also
specify the JVM that you will use for the maven-surefire-plugin (which by
defaults, handles the test phase of your build) ( see [3] ).
Cheers,
Franz

Hi,

I'm using JDK1.5.0_08, but Maven uses 1.3, but 1.4, as default.

Re: Setting up a new jre to maven
Posted by Wayne Fay <wa...@gmail.com>.
Yes, to compile 1.5 classes, you must use a 1.5 (or greater) JRE. But
you also must set the 1.5 configuration, otherwise it defaults to 1.4
classes with the 1.5 JRE.

Hello,

> </configuration>
If that's true, I'm confused by the settings.
Why Maven(or javac) can compile sources to 1.5-compatible classes at
1.4.2JRE(or 1.4.2 javac)?
In order to fulfil the requirement, I think must install JDK1.5 firstly.
Then use the real jre1.5.0 and configuration quoted above.
a cup of Java, cheers!

Hi Allan,
Add these lines to you pom.xml:
<project>
<build>
<plugins>
<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.5</source>
<target>1.5</target>
</configuration>

Re: Setting up a new jre to maven

Yes, you naturally need to use a compiler at least as high as the code you
wish to compile in. If your Maven is running on JDK 1.4, and you wish to
compile code as 1.5, you will need a 1.5 compiler. You can point to a
1.5compiler in the following way:
