Using alternative JDK
Hi!
How can I tell for one specific pom use a JDK different from my
JAVA_HOME for a compilation?
Thank you!

Hi Niels,
Or, if you for some obscure reason need jdk 1.3:

> <configuration>
> <fork>true</fork>
> <executable><your-jdk1.3-javac.exe></executable>
> <compilerVersion>1.3</compilerVersion>

> </plugin>
Did you try this [1] ?
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.3</source>
<target>1.3</target>
<compilerArguments>
<bootclasspath>${settings.localRepository}/com/sun/rt/1.3.1_08/rt-1.3.1_08.jar</bootclasspath>
</compilerArguments>
</configuration>
<dependencies>
<dependency>
<groupId>com.sun</groupId>
<artifactId>rt</artifactId>
<version>1.3.1_08</version>
</dependency>
</dependencies>
</plugin>

<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<fork>true</fork>
<executable><your-jdk1.3-javac.exe></executable>
<compilerVersion>1.3</compilerVersion>
</configuration>
</plugin>
AND if for some other obscure reason use w2k OR have very many source
files, the forked compiler command line will blow up and fail.
There you will need a compiler component that will provide the source
file names as a @ argument to javac.
Who said m2 was easy?

I have this in my pom. The problem went away though when I removed an
exclusion (commons-validator) from another dependency. This dependency
doesn't use it, so it seems strange to me.
But it works, so all is good. :)
Thanks!

It seems you're missing a dependency in your pom.xml....:
<dependencies>
...
<dependency>
<groupId>commons-validator</groupId>
<artifactId>commons-validator</groupId>
<version>1.3.1</version> <!-- or whatever version you need -->
</dependency>
</dependencies>

The NotImplementedException I can fix, but the error regarding
org.apache.commons.validator remains a mystery to me.

What error messages do you get? Have you tried "mvn -e -X ..."?

Hi!
My build fails if java1.6 is used instead of java1.5. (No java1.6
specific functionality is employed.)
Shouldn't the following configuration fix this?
<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.5</source>
<target>1.5</target>
<encoding>UTF-8</encoding>
</configuration>
</plugin>
If "yes", what else can be wrong?

Hi all,
Be aware of that configuration [1]
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.4</source>
<target>1.4</target>
</configuration>
</plugin>
[1]
http://maven.apache.org/plugins/maven-compiler-plugin/examples/set-compiler-source-and-target.html
means you want the compiled classes to be compatible with JVM 1.4 (-target
1.4) not that you compile with the JDK 1.4.
It's not the same. For example, if you use some specific Java5 API without
any specific Java5 token (enum, annotation...), you can compile your
classes with a JDK 1.5 with a target 1.4 but not with the JDK 1.4.
If your really want to compile with an other JDK you need to specify the
rt.jar appropriate like this [2]
<configuration>
<source>1.4</source>
<target>1.4</target>
<compilerArguments>
<verbose />
<bootclasspath>${java14.home}/lib/rt.jar</bootclasspath>
</compilerArguments>
</configuration>
