Eclipse Helios (3.6)
Acceleo 3.0.1.v201009150438

Am setting variables from a property file.
Everything worked fine until I tried the following syntax.

Any guidance is appreciated.

[comment encoding = UTF-8 /]
[module activator('http://www.eclipse.org/emf/2002/Ecore')/]

[template public activator()
{
packageBase : String = getProperty('propfile.properties','org.anorg.eclipse.plugin. packageBase');
projectName : String = getProperty('propfile.properties','org.anorg.eclipse.plugin. name');
}]
[file ([packageBase/].Activator.java, false, 'UTF-8')]
package [packageBase/];
[/file]

[/template]

--------------------------------
1. In the module editor, no errors are indicated.
2. When i execute acceleo (as java application), receive abnormal termination 'Acceleo Evaluation Exception' and a stack trace:

--------------------
Then an error appears, in the module editor, under the opening parenthesis in the opening [file statement and another error on the closing file statement [/file] saying 'The invocation isn't terminated'.

Hi Rich,

"Unresolved compilation error" means just that : you have compilation errors in the module. And indeed, the compiler would throw syntax exceptions in numerous places of this module. I believe you don't have the automatic build activated (Project > Automatic build) in your Eclipse, or you would have seen all of these.

Please read the documentation available in Eclipse Help > Help Contents or online for basic information on the syntax.

[template public activator()]
{
[let packageBase : String = getProperty('propfile.properties','org.anorg.eclipse.plugin. packageBase') ]
[let projectName : String = getProperty('propfile.properties','org.anorg.eclipse.plugin. name')]
[file (packageBase + '.Activator.java', false, 'UTF-8')]
package [packageBase/];
[/file]
[/let]
[/let]
[/template]
