Summary: SQL task closes its output even if it is System.out
Product: Ant
Version: 1.7.1
Platform: PC
OS/Version: Windows XP
Status: NEW
Severity: normal
Priority: P2
Component: Core tasks
AssignedTo: [email protected]
ReportedBy: [email protected]
If not value is specified for outptut attribute of the SQL task it takes
System.out as default output which is correct. But when SQL tasks finishes it
closes its output regardless of what kind of output it uses.
As a result after SQL taks executes there will be no more output from any code
that uses System.out
Here is the source code form 1.7.1 distribution that shows the problem (in
execute() method):
-----------------
PrintStream out = System.out;
try {
if (output != null) {
log("Opening PrintStream to output file " + output,
Project.MSG_VERBOSE);
out = new PrintStream(new BufferedOutputStream(
new FileOutputStream(output.getAbsolutePath(),
append)));
}
// Process all transactions
for (Enumeration e = transactions.elements();
e.hasMoreElements();) {
((Transaction) e.nextElement()).runTransaction(out);
if (!isAutocommit()) {
log("Committing transaction", Project.MSG_VERBOSE);
conn.commit();
}
}
} finally {
FileUtils.close(out); //<<<<---- closes output even if it
is System.out
}
