Subject [jira] Created: (IVY-605) XmlReportOutputter not safe
Date Tue, 18 Sep 2007 15:19:43 GMT
XmlReportOutputter not safe
---------------------------

                 Key: IVY-605
                 URL: https://issues.apache.org/jira/browse/IVY-605
             Project: Ivy
          Issue Type: Bug
          Components: Core
            Reporter: Jean-Baptiste Quenot


When issuing several "resolve" task in parallel on several projects having the *same* Ivy
file, it may happen that the generated XML reports in ivy cache are overwritten.  And thus
at a given moment in time, this file may appear empty, as FileOutputStream overwrites the
destination directly.  When using the "report" task (also in parallel), this leads to the
following error:

{noformat}
[ivy:report] Transforming into /path/to/myproject/target/ivy-reports
[ivy:report] Processing /path/to/ivy-cache/myproject-compile.xml to /path/to/myproject/target/ivy-reports/myproject-compile.html
[ivy:report] Loading stylesheet /path/to/ivy-cache/ivy-report.xsl
[ivy:report] Processing /path/to/ivy-cache/myproject-default.xml to /path/to/myproject/target/ivy-reports/myproject-default.html
[ivy:report] : Error! Premature end of file.
