Hello everyone.
I've created my own listener CustomXmlLogger that is a child of XmlLogger
and packed it in VCS.jar. I don't want to copy it to ANT_HOME/lib so I tried
to include a reference to the archive in my Ant call.
But I've got a problem. When I launch a build Ant indicates on LinkageError:
"C:\Program files\Java\jdk1.5.0_08\bin\java.exe" -classpath
c:\bin\apache-ant-1.7.0\lib\ant-launcher.jar;VCS.jar
-DXmlLogger.file=build_tes
t_log.xml -DXmlLogger.level=WARN -Dant.home=c:\bin\apache-ant-1.7.0
org.apache.t
ools.ant.launch.Launcher -listener
com.kvazarmicro.umc.vcs.utils.CustomXmlLogger
Buildfile: build.xml
BUILD FAILED
Class com.kvazarmicro.umc.vcs.utils.CustomXmlLogger could not be loaded
because
of an invalid dependency.
When I added ant.jar the error was different:
D:\home\UMC\.garbage>"C:\Program files\Java\jdk1.5.0_08\bin\java.exe"
-classpath
c:\bin\apache-ant-1.7.0\lib\ant-launcher.jar;c:\bin\apache-ant-1.7.0\lib\ant.jar;VCS.jar
-DXmlLogger.file=build_test_log.xml -DXmlLogger.level=WARN -Dant.home=
c:\bin\apache-ant-1.7.0 org.apache.tools.ant.launch.Launcher -listener
com.kvazarmicro.umc.vcs.utils.CustomXmlLogger
Buildfile: build.xml
test:
[delete] Deleting directory D:\home\UMC\.garbage\build
[mkdir] Created dir: D:\home\UMC\.garbage\build
[javac] Compiling 1 source file to D:\home\UMC\.garbage\build
BUILD FAILED
D:\home\UMC\.garbage\build.xml:14: Unable to find a javac compiler;
com.sun.tools.javac.Main is not on the classpath.
Perhaps JAVA_HOME does not point to the JDK.
It is currently set to "C:\Program files\Java\jdk1.5.0_08\jre"
My JAVA_HOME is set to "C:\Program files\Java\jdk1.5.0_08" and Ant finds
compiler perfectly if I don't use my listener.
So I have a question: how can I use a custom listener not copying it in
ANT_HOME/lib?
Source of the listener:
import org.apache.tools.ant.BuildEvent;
import org.apache.tools.ant.Project;
import org.apache.tools.ant.XmlLogger;
public class CustomXmlLogger extends XmlLogger {
@Override
public void buildStarted(BuildEvent event) {
super.buildStarted(event);
String levelStr = System.getProperty("XmlLogger.level");
if (levelStr != null) {
int level;
if (levelStr.equalsIgnoreCase("ERR")) {
level = Project.MSG_ERR;
} else if (levelStr.equalsIgnoreCase("WARN")) {
level = Project.MSG_WARN;
} else if (levelStr.equalsIgnoreCase("INFO")) {
level = Project.MSG_INFO;
} else if (levelStr.equalsIgnoreCase("VERBOSE")) {
level = Project.MSG_VERBOSE;
} else {
level = Project.MSG_DEBUG;
}
setMessageOutputLevel(level);
}
}
}
