How do I make eclipse 3.0.1 support new language features of JDK1.5?

[debbie_82]

I have just downloaded the latest eclipse version 3.0.1 and I also have the latest jdk1.5... and I've been encountering quite a number of problems.

Eclipse it seems cannot understand the new language features.
I have been trying to do a little bit of coding about the foreach loop construct (new to jdk1.5) and well eclipse always says syntax error.

Is there anyway the syntax checker be updated to support java1.5 new language features?
and it won't run...

I did try doing that code on notepad so that syntax is not yet checked during that time and used the command line to execute my code and well that one worked.. so I guess the problem is eclipse itself..

Is there some available patches for these? I don't know how to look for them... Even jbuilder has some problems with the jdk1.5 version... I don't know what to do.

I can't see myself doing notepad and the command line all the time...

P.S.
How does eclipse process java source files anyway?

In the Preferences -> Java -> Compiler -> Compliance and Class Files

There is an item there with Compiler Compliance Level
and has drop down values... selected is 1.4... could this be the cause of the problem? that all source must comply with 1.4 thus 1.5 new lang features cannot be recognised?

I'm just wondering.

NVM

I just read an article and well it says there that support for J2SE 1.5 "Tiger" will be supported in the next year's Eclipse release 3.1

I guess I just have to refrain from using the new language features if I can...

Or use another IDE...

Or use an ANT build.xml file -- and ignore the syntax checking.

<project name="java15" default="all" basedir=".">
	<target name="build">
		<depend srcdir="."></depend>
		<javac srcdir="." source="1.5">
			<compilerarg value="-Xlint"/>
		</javac>
	</target>
</project>
