Printing Ant target execution time - ant

I want to print the execution time taken for each individual Ant target and its dependent targets.
<target name="target1" depends="target2, target3">
....
</target>
When run should show following output
Target 2 - x seconds
Target 3 - y seconds
Target 1 - z seconds
Any suggestions on how to achieve this?

Since Ant 1.8.0 you can use a profilelogger to do this.
ant -logger org.apache.tools.ant.listener.ProfileLogger target
Produces output like
Target aTarget: started Thu Jan 22
09:01:00 CET 2009
echo: started Thu Jan 22 09:01:00 CET
2009
[echo] echo-task
echo: finishedThu Jan 22 09:01:00 CET
2009 (250ms)
zip: started Thu Jan 22 09:01:00 CET
2009
[zip] Building zip: ...\my.zip
zip: finishedThu Jan 22 09:01:01 CET
2009 (1313ms)
Target aTarget: finishedThu Jan 22
09:01:01 CET 2009 (1719ms)

Use one of the listeners from Ant add-on task collections:
antutility
antelope
antcontrib
With -listener net.sf.antcontrib.perf.AntPerformanceListener
Or check their sources, and roll your own listener.

If you're using ant-contrib, then there is a stopwatch task. Put it at the top and bottom of each target and it will report the elapsed and total times.
http://ant-contrib.sourceforge.net/tasks/tasks/index.html

There is the TStamp task that you can use to demark your other tasks.
See here: http://ant.apache.org/manual/Tasks/tstamp.html
There is some extension/addon that will do it all for you without having to do this. Will scrabble around for it if no-one comes up with it first.

highcharts-export-server always produces blank PNG

I'm trying to use highcharts-export-server in command-line/batch mode. I've installed the latest version (2.0.28). I'm running Windows 10 with Node 12.
I'm running it from the command line using the following command:
highcharts-export-server --nologo 1 --logLevel 4 --options chart.json --outfile chart.png --type png --width 500
The console output says:

...but although a chart.png file is created and has the correct width, it's blank (transparent):
This is the content of the chart.json file, which I took from one of the examples on the Highcharts website:
{
chart: {
type: 'bar'
},
title: {
text: 'Fruit Consumption'
},
xAxis: {
categories: ['Apples', 'Bananas', 'Oranges']
},
yAxis: {
title: {
text: 'Fruit eaten'
}
},
series: [{
name: 'Jane',
data: [1, 0, 4]
}, {
name: 'John',
data: [5, 7, 3]
}]
}
Note: I'll mention that when I first tried to install highcharts-export-server I hit a different problem which was that I couldn't run it at all (it failed with uncaughtException: TypeError: "file" argument must be a non-empty string). After some googling I found some blog posts suggesting that I needed to install PhantomJS first, and to use the --unsafe-perm option. So, the commands I actually used to install it was:
npm install phantomjs --unsafe-perm
npm install highcharts-export-server --unsafe-perm
Oh, and it wasn't until some time later that I realised I might have to install Highcharts itself :-) So I did that too (npm install highcharts), but it didn't actually seem to make a difference.
In case this helps anyone else, here is the full conversation about this issue on the Highcharts Forum.
In summary, it turned out that the NPM package was improperly installed (due to a firewall issue).
This wasn't apparent from the installation logs, but the effect was that in the node_modules/highcharts/export-server/phantom/export.html file there was a script block that should have contained minified JavaScript but that actually contained only lines saying undefined;.
The fix in my case (to work around the firewall issue) was to specify an http URL for the CDN when installing Highcharts Export Server, rather than the default URL which uses https. Once I'd done that, the export.html did contain the minified JS code, and the tool worked correctly.

How to build up a ML model for text classification which contains none 'natural language'?

I am looking for a model for text classification for our log notes analytics.
The challenge is that each note may contain none 'natural language' texts. For example, some notes are thread backtrace output with symbols, some notes are logging information from source code. And among these notes, some notes with description of how customer is using our product are the ones we want to classify.
Is there any ML model or approach that I could use for this text classification?
Below are some examples for different notes (I changed some content so no company confidential materials are shown):

Jenkins - changes exists in SVN, but Jenkins show no changes, but build is running

I had scheduled pulling in Jenkins every 5 minutes: */5 * * * *.
I committed changes to SVN, I can see them in SVN history (logs).
Jenkins starting the build, but it shows: Revision: x
No changes. And everything what was configured is running.
After 5 minutes Jenkins starts another run, with message: Revision: x+1
Changes

by UserName
After, for test purposes I have changed to * * * * * to run every minute, and the results were such:

It is strange behavior, could someone have idea, where could be the issue?
Based on the conversation, We have found out the culprit was the Time Difference of the 2 servers(Jenkins and SVN) approx 7-8 mins was the issue.
Why does this happen ?
Jenkins realized that a new version was available, but couldn't check it out
as long as its own time was smaller than the new versions time.
A similar issue is described here:
Why up-to-date files committed to SVN will not be immediately pulled out by Hudson to build

Jenkins - java.lang.OutOfMemoryError: PermGen space -

Environment: Linux/Windows7, Java 1.6.0.03/37 or 1.7
I downloaded jenkins.war and after the initial setup using the following script/command, I downloaded some plugins(10-15) and tried to restart Jenkins, it worked. Then, I got some more plugins (30-40 in total) and either I chose Install or download+then+install, Jenkins didn't come up.
i.e. using startJenkins.sh (Linux only). Note: On Windows7 Jenkins started as a Windows service.

How can I resolve this issue? The same issue came up when I did the same exercise on my Windows desktop machine. Do I need to use less or a limited number of plugins?
Thanks
In my ~/.bash_profile file, I have set the following 3 variables. Note there are other variables in this file as well i.e. JAVA_HOME, ANT_HOME, SONAR_HOME, SONAR_RUNNER_HOME, etc:
export JAVA_OPTS="-XX:MaxPermSize=512m -Xms512m -Xmx1024m"
export GRADLE_OPTS="-XX:MaxPermSize=512m"
export SONAR_RUNNER_OPTS="-Xmx512m -XX:MaxPermSize=512m"
All - working now.
The first export line: will get Jenkins going without PermGen error, the 2nd line will make Gradle going when Jenkins calls Gradle script (via a another wrapper script for ex. .sh/etc), third line makes "sonar-runner" command to work fine (otherwise, I was getting an error for PermGen after "Initialize Hibernate"... line during sonar-runner command's output). You run sonar-runner command in the workspace where you have compiled java, reports related to static code analysis tools (pmd/checkstyle/findbugs) and other code coverage reports (jacoco/cobertura). Workspace should have "sonar-project.properties" file. Look for SonarQube help pages about this file and what all variables it contains for a project.
All those options are documented here:
http://docs.oracle.com/javase/8/docs/technotes/tools/windows/java.html
or here if you are using Java 7:
http://docs.oracle.com/javase/7/docs/technotes/tools/windows/java.html
IF you are using Gradle, You can set the -Xmx or -XX:MaxPermSize by adding a GRADLE_OPTS global environment variable in the Jenkins global configuration. To do this, click Manage Jenkins, then Configure System. In the Global properties section, click the Environment Variables checkbox, then add a new environment variable called GRADLE_OPTS with the value set appropriately as below:
name: GRADLE_OPTS
value: -Xmx1024m -XX:MaxPermSize=1024m
where 1024 is memory specified. You can change it as per your requireent.
Similar configuration is needed for Maven. Please see the link below for more details:
