I am using the import task in Ant to bring in some shared targets into my build script.  When I first open the build.xml file it is ok, but when edit it and the file is reparsed I get the following problems:

- Each part of the file is shown in the outline view with [from null] at the end e.g from the files below
"test {from null]"
"imported-target [from import build-shared-targets.xml [from null]]

- When I edit the file it no longer indents properly when I add new lines of code
- An error is displayed in the problems window for targets used which are in the imported file (this happens in my real buildfile, but not in my simple reproduction script below)
- A warning is displayed in the problems window because it cannot find the import file (this happens in my real buildfile, but not in my simple reproduction script below)
- The following stack trace was produced in the error log:

Error logged from Ant UI:

Session data:
eclipse.buildId=M20060921-0945
java.version=1.5.0_06
java.vendor=Sun Microsystems Inc.
BootLoader constants: OS=win32, ARCH=x86, WS=win32, NL=en_GB
Command-line arguments:  -os win32 -ws win32 -arch x86

Here are the build scripts I used to reproduce this:

<project name="importer" basedir=".">
	
	<import file="build-shared-targets.xml"/>
	
	<target name="test" depends="imported-target" >
		<echo message="test" />
	</target>
	
</project>

<project name="imported" >

	<target name="imported-target">
		<echo message="imported target" />
	</target>
	
</project>

Even if the outline view has been broken, and their are errors in the problems window, the build file still works fine.

Workaround: close the editor window and reopen it.  The outline will be correct. Once you edit something it will break.
