| Merging of import statements not working? [message #33742] |

Given that I have a JET template that uses <java:import> to add the import
statements for classes that are in the emitted code, and merging is turned
on (i'm using jmerge), the transformed file will always contain the import
statements of the existing file, not the ones from the emitted and merged
code from JET. I tried to use <merge:pull sourceGet="Import/getName"
targetPut="Import/setName"/> but to no avail. Is there a merge rule that I
need to add to be able to merge the import statements? Btw, I'm using JET
0.7.3 and JMerge (org.eclipse.emf.codegen) 2.2.2.
Thanks,
Francis

Francis:
Some observations...
1) the position of java:merge in your template should have no impact - it is
merely a marker that indicates the final buffer contents should be passed
through JMerge.
2) The standard JMerge rule for imports would add any imports from the
expanded template into the imports of the existing file. No imports would
ever be removed. There is some logic to this, as the existing files inputs
could arise from user written code.
3) Sorting in jmerge is controlled by <merge:sort> elements in the rules
file. There is not one for Imports in the standard rules file
( http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.emf/org .eclipse.emf/plugins/org.eclipse.emf.codegen.ecore/templates /emf-merge.xml?revision=1.12&root=Modeling_Project&v iew=markup),
but if sorting is important, I'd experiment with
<merge:sort select="Import"/>
