http://issues.apache.org/bugzilla/show_bug.cgi?id=31969 Mail tasks depends on Java verifier Summary: Mail tasks depends on Java verifier Product: Ant Version: 1.6.2 Platform: PC OS/Version: Windows XP Status: NEW Severity: Normal Priority: Other Component: Core tasks AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] When the Mail task is used with the encoding set to "auto", it attempts to determine if MIME is available by calling Class.forName() on the org.apache.tools.ant.taskdefs.email.MimeMailer class. If this succeeds, it assumes MIME mail is available and tries to use it. However, the success of this operation will depend on the presence of the Java verifier. This code has a "catch (Throwable e)". When the verifier checks the MimeMailer class, it will also check for the dependancy classes javax.mail.MessagingException and javax.activation.DataSource classes. These will only be found if the mail.jar and activation.jar are on the classpath. If they are not, a VerifyError is thrown and the catch clause will fire. It will then default to the UU encoding, and the build will succeed, which is the correct behavior for the auto encoding. However, if the verifier is not being used in the VM, then the Class.forName() will check for the existance of the MimeMail class, but not the MessagingException and DataSource classes. If the mail.jar or activation.jar is missing from the classpath, no error is thrown, the catch clause will not fire, and it will continue on its way assuming that it should use MIME. Later, it will fail with a NoClassDefFoundError on the MessagingException and DataSource classes and the Ant build will fail. To reproduce: 1) Set your ANT_OPTS environment variable to "-Xverify:none" 2) Try to run an Ant buildfile using the mail task with encoding set to "auto" 3) You will see a NoClassDefFoundError and the build fails This is a problem for IDE's, which may not be running with the verifier. If they try to run Ant in the same VM as the IDE, the mail task will fail. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
