[launching] Resolve Java path

[eclipse-qvtd-bot]

Description

The new launch dialog offers a free choice of Java file path based on the original Tx file path, which may or may not be correlated with an original Tx pivot-Package path. Probably not since the pivotPackage path is relatively new.

Since these two conflict; the launch temporarily disables the Java aspects.

Suggest:

The default Java folder should be the first classpath of the JavaProject, with the class file its corresponding binary folder. Within those folders the filename should be the pivotPackage/Class path suffixed by .java/.class.

This probably requires a minor revision of the Tx chain to support pivot-Package-paths correctly.

Since there are many paths in the dialog, treat blank as an entry/persistence default so that changes to a source propagate. Perhaps italics when the default.

Most of the problems go away when the Java/Class values are typically .../src-gen and .../bin without subsequent detail, and when a default project eliminates the need for prefix as well.

Re-enabled with a plausible QVTc and QVTr launch example for RC3.

A specific problem occurs for the manual choice of names for testQVTcCompiler_Families2Persons_CG

java.lang.ClassNotFoundException: E:\GIT\org.eclipse.qvtd\tests\org.eclipse.qvtd.xtext.qvtcore.tests\bin\org\eclipse\qvtd\xtext\qvtcore\tests\families2persons\Families2Persons.class (The system cannot find the file specified)\ \ since org.eclipse.qvtd.xtext.qvtcore.tests.families2persons.Families2Persons is also the name of a middle model package name.

This problem is suppressed by imposing a "cg." prefix for the tx class.

Another specific problem occurs for

import '../../../../../../../../../../org.eclipse.qvtd.pivot.qvtrelation/model/QVTrelation.ecore#P-qvtrelation'; ...\ transformation org::eclipse::qvtd::xtext::qvtrelation::tests::atl2qvtr::ATL2QVTr ...\ new:qvtr relTx : qvtrelation::RelationalTransformation[1];

The reference to "qvtrelation" could be:

• the Model package in QVTrelation.ecore
• an ancestor Java package in org::eclipse::qvtd::xtext::qvtrelation::tests::atl2qvtr

The wrong one is used.
