Attempt to build JFreeChart-FSE fails

[mrubin]

Following Dave Gilbert's steps for building the JFreeChart-FSE project, I attempted to do so on my Windows machine. The build seemed to succeed, failing on only four Surefire tests (I will try to attach the debug log, but if not you'll find it here).

Although the four tests failed, I expected to find the jfreechart-fse-1.0-SNAPSHOT.jar file, or any other JAR file for that matter, but there are none. What am I doing wrong?

Looking at the [INFO] lines in the log shows:

The build failure seems related to the four failed Surefire tests. Would that cause the JAR file to be deleted?

It looks like the build is failing because the unit tests don't all pass. I'll fix that, but in the meantime you could skip the tests:

Code: Select all

mvn clean install -DskipTests=true

Hi David,

Many thanks for the prompt reply. Indeed, when skipping the tests, the JAR file builds correctly and stays around.

I am, however, experiencing problems running the demo classes:

• org.jfree.chart.demo
• org.jfree.chart.demo.selection
• org.jfree.chart.fx.demo

Three demos in org.jfree.chart.demo ran correctly, while ApplicationFrame needs needs a main(). All other demos threw exceptions, see the following output log:

Exception running application org.jfree.chart.fx.demo.TimeSeriesChartFXDemo1

I would very much like to examine the selection demos to understand the lassoing method better. Can the FSE demos be fixed to enable that?

Thanking you in advance,

Moshe

[david.gilbert]

Hi,

I committed the fixes for the junit tests so if you update you should be able to build with the tests enabled.

When I try running the demos, I get the same error as you for the JavaFX demos but all the others run correctly (except ApplicationFrame which is a support class, not a demo application). I'll fix the JavaFX stuff hopefully tonight. Can you check that you don't have any local changes that could be causing the runtime exceptions?

[mrubin]

Hi Dave,

Many thanks for committing the junit test fixes. I will carefully check my FSE installation and compilation, including my Java JRE/JDK settings and paths, etc. I will get back to you as soon as I have findings to report.

Regards,

Moshe

[mrubin]

Hi Dave,

In answer to your question about why my JFreeChart-FSE demo classes are throwing exceptions, I'm happy to report that everything works correctly with no exceptions. Indeed, as you suggested, I checked the java environment. I noticed that the JRE and JDK versions, although both 1.0, were not the same revision. I cleaned up my Java environment by deleting older JRE/JDK installs, leaving only JRE/JDK 1.8.0._91. Now the FSE demo classes work flawlessly.

I'm about to integrate FSE into my existing projects and will post any issues, if they occur.

Thank you very much for your help and insights,

Moshe
