Java source files are not copied when "optimizationLevel" is set to "SIMPLE"

Hi:

When you use the plug-in for Maven and set the optimizationLevel option to SIMPLE, the plug-in does not copy the Java source files to the target directory; it only copies the source maps. These are the most relevant options of my configuration:

...
<sourceMapsGenerated>true</sourceMapsGenerated>
<sourceFilesCopied>true</sourceFilesCopied>
<optimizationLevel>SIMPLE</optimizationLevel>

If you set optimizationLevel to ADVANCED or FULL, though, the source files are effectively copied there.

This happens in version 0.6.1 and also 0.7.0-dev-1105.

The only workaround that has came to my mind is to compile first in ADVANCE level and then in SIMPLE level. But it’s tiring when you need to do multiple clean-then-build actions.

Thank you.

Ok, but writing a documentation requires some time and efforts from my side which I don’t have. So in brief you need teavm-cli artifact. To build it, you need to enable with-cli Maven profile. CLI module is located at tools/cli directory. Also, you can download this artifact from bintray (for example, current latest one is https://bintray.com/konsoletyper/teavm/download_file?file_path=org%2Fteavm%2Fteavm-cli%2F0.7.0-dev-1105%2Fteavm-cli-0.7.0-dev-1105.jar).

Run

java -cp teavm-cli-0.7.0-dev-1105.jar org.teavm.cli.TeaVMDevServerRunner

from command line and you’ll get some help.

You’ll need to specify following options:

java -cp teavm-cli-0.7.0-dev-1105.jar org.teavm.cli.TeaVMDevServerRunner \
  package.name.MainClassName \
  -p classpath-element1 \
  -p classpath-element2 \
  -s source-element1 \
  -s source-element2 \
  --deobfuscate-stack \
  --indicator

And dev server will serve generated Javascript at http://localhost:9090/classes.js. Classpath elements are either directories (path/to/module/target/classes or jar files). Each time .class files are updated, TeaVM will pick these changes and rebuild Javascript.

I fixed the issue. However, I see that your are trying to use Maven for development cycle, which is inefficient. I’m going to remove incremental mode from Maven build at all. You can try to use dev server available on IDEA plugin (which has really efficient incremental compilation and performs deobfuscation of stack traces and allows debugging right in IDEA) or if IDEA is not an option for you, ask me and I provide further instructions to setup CLI version of dev server.
