-----------------------------
> Maven2 plugin fails to detect that schema was changed when generating om, etc
> -----------------------------------------------------------------------------
>
> Key: TORQUE-118
> URL: https://issues.apache.org/jira/browse/TORQUE-118
> Project: Torque
> Issue Type: Bug
> Components: Maven 2 Plugin
> Affects Versions: 3.3
> Environment: OS: Linux 2.6.24.4-64.fc8
> JDK: jdk1.6.0_07
> Maven: apache-maven-2.0.9
> Reporter: Mitri Hanania
> Priority: Minor
> Fix For: 4.0-beta1
>
>
> Using the Maven2 plugin, generate the OM classes from a schema file. Then
> make a change to the schema file and try to re-generate the OM classes. The
> Maven2 plugin will state that the schema has not changed with respect to the
> report file.
> After debugging, it seems that the method schemaChanged() in class
> org.apache.torque.mojo.DataModelTaskMojo attempts to compare the last
> modified dates between the schema file and the report file. It uses the
> classes FileSet and DirectoryScanner to obtain a list of schema files to
> compare against the report file. The method
> DirectoryScanner.getIncludedFiles() is called to return a list of schema
> files in the directory specified by the "schemaDir" property. According to
> the javadocs, DirectoryScanner.getIncludedFiles() returns a list of file
> names relative to the "base" directory. However, the file names are being
> used as if they are absolute file names when trying to retrieve the last
> modified time. Hence, always resulting in a last modified time of 0, which
> causes the schema file to alway fail when comparing to see if the schema file
> has a last modified time greater than the report file.
> A work around that I have been using is to always delete the report files
> when a change is made to the schema file.
> A proposed fix is to create the schema java.io.File object using the
> "schemaDir" property and the relative file name:
> for (int i = 0; i < fileNames.length; ++i)
> {
> File file = new File(schemaDir, fileNames[i]);
> if (file.lastModified() > report.lastModified())
> {
> schemaChanged = true;
> break;
> }
> }
