[sakai2-tcc] Java 1.6 and Sakai 2.9

[Maurer, Christopher Wayne]

The 2.6.x build is the only one using 1.5, all the rest are on 1.6 so shouldn't make any difference to nightly2!

Subject: Re: [sakai2-tcc] Java 1.6 and Sakai 2.9

Next Tuesday I plan to reconfigure the purepoms compiler plugin to compile with 1.6 (locally) and see how the indies behave when I compile them.  If they compile without complaint when I run

mvn compile

I'll test the rest of trunk.  If trunk behaves then perhaps we set the date between Wed-Fri, 1-3 December.  The date should be coordinated with Chris--not sure if Nightly2 build scripts require any adjustment.

I plan to use version 2.3.2 of the compiler plugin (and specify the version in the <plugin> entry).


<plugin>
<inherited>true</inherited>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.6</source>
<target>1.6</target>
</configuration>
</plugin>

Cheers,

Anth

As mentioned on the source install guide, "Oracle's Sun Java SE
6<http://java.sun.com/javase/6/>, a.k.a Java 1.6, is the
preferred version to use with Sakai 2.7." [1] However there is
still some confusion about what this means. As we know Java 5
is nearly a year now past the End of Life (11/09) and also
harder to find for new people looking for it.

We definitely need to clarify this for the 2.8 release. If no QA
servers are running or building under 1.5 -- I am ignoring the
target versions discussion for now -- then we can be more
confident in making a statement along the lines of "we recommend
1.6 and that's what this thing was QA'd on."

I have sent somemail to the qa-admins list about the use of 1.6.

I agree with Seth that we should:

* Make the decision to switch the compilation for trunk (2.9) to 1.6. Sakai
after this version will no longer be guaranteed to be compatible with
JDK/JRE 1.5 and apis/methods/libraries specific to 1.6 could be used if
necessary.

Anyone have a suggestion for a date to move over definitely to
1.6 in trunk? We could just announce a hard cutover to
identify/re-confirm the problem points that exist even with the
workarounds.

Seth
