DO NOT REPLY [Bug 50091] New: task referring to
installed optional packages with nested
fails with NoClassDefFoundError
https://issues.apache.org/bugzilla/show_bug.cgi?id=50091
Summary: <java jar=".."> task referring to installed optional
packages with nested <jvmarg
value="-Djava.ext.dirs=.."/> fails with
NoClassDefFoundError
Product: Ant
Version: 1.8.1
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2
Component: Core tasks
AssignedTo: notifications@ant.apache.org
ReportedBy: anhalter42@gmx.net
Created an attachment (id=26174)
--> (https://issues.apache.org/bugzilla/attachment.cgi?id=26174)
sample project to illustrate the problem
testcase:
I have two classes in two jars. Both jars are located in the lib directory.
Using
<java jar="lib/main.jar" fork="true" failonerror="false" dir=".">
<jvmarg value="-Djava.ext.dirs="lib""/>
</java>
fails with NoClassDefFoundError
Using deprecated syntax
<java jar="lib/main.jar" jvmargs="-Djava.ext.dirs="lib"" fork="true"
failonerror="false" dir="."/>
works just fine.
On Windows platform the issue doesn't occur.
Seems to be a sequencing issue when building the commandline: -Djava.ext.dirs
has to preceed the -jar option.
Attached is a sample project to illustrate the problem.
My platform: Ubuntu Linux 10.4, 2.6.32-24-generic kernel, x86_64

OK, got it.
Works fine for me w/o quotes on both Linux and Windows.
Thanks!

JRE version doesn't matter - happens with both 1.5.0_22 and 1.6.0_20

the "depreacted" jvmargs attribute strips away the quotes that aren't
needed anyway.
using
<jvmarg value="-Djava.ext.dirs=lib"/>
things work fine (for me on Linux where the version with quotes fails).
You are setting a Java property and there is no directory called "lib" (with
the quotes as part of the name). On Windows different command line parsing
rules apply, that's why it works there.
If your directory cotained spaces you wouldn't need quotes either since
Ant uses a String[] version of exec() and thus the CLI won't erronously split
things.
