Subject: IJavaProject.setRawClasspath, IJavaProject.setOutputLocation -
undesirable effect of copying of all resources from old output location to
new output location IJavaProject.setOutputLocation
Hi,
Can you explain why IJavaProject.setRawClasspath and
IJavaProject.setOutputLocation now copy all resources from
old output location to new output location ?
It seems that someone else also is not sure if this is the right thing to
do :
Here is the comments in BatchImageBuilder.copyExtraResourcesBack.
protected void copyExtraResourcesBack(ClasspathMultiDirectory
sourceLocation, final boolean deletedAll) throws CoreException {
// When, if ever, does a builder need to copy resources files (not .java or
.class) into the output folder?
// If we wipe the output folder at the beginning of the build then all
'extra' resources must be copied to the output folder.
This has a very undesirable effect on the data definition view within the
Data perspective. The following example illustrates the problem.
1. Go to Java perspective.
2. Create a Java project (e.g. myjavaproj) and take all the defaults. The
default output folder is set to the project folder.
3. Go to Data perspective.
4. From Data Definition view, create DB, Schema, a table, a default SQL SP
in the project from step 1.
5. Go back to the Java perspective
6. Bring up the properties dialog of the Java project.
7. Change the Default output folder to myjavaproj to
myjavaproj/myoutputdir . myoutputdir does not exist yet.
Press OK.
All resources including the EMF persistence files for the database
objects such as .dbxmi, schxmi, .tblxmi, .spxmi, are
copied from the old output location (myjavaproj) to the new output
location (myjavaproj/outputdir ).
8. Go back to the Data Definition. Now the data elements are replicated in
the myjavaproj/myoutputdir because
the EMF persistence files (.dbxmi, .schxmi, etc) were copied into the
new output location (myjavaproj/myoutputdir).
These files have special significance to the data view and should not
have been copied to the new output location.
Please let me know if IJavaProject.setRawClasspath and
IJavaProject.setOutputLocation will be changed so they
do not copy files that may have other significance to other plugins.
Thanks.
