Hi,

Does --limit-modules work as intended, are there any tests?
With a command such as:

jpackager -Djlink.debug=true create-image \
    --input out/artifacts \
    --output out \
    --limit-modules java.base \
    --main-jar Hello-jar/Hello.jar \
    --class Main

It complains that:
Exception: jdk.tools.jlink.plugin.PluginException: java.lang.module.FindException: Module jdk.compiler not found, required by jdk.jdeps

After adding a few more modules it stops complaining about missing dependencies:      --limit-modules java.base,jdk.compiler,jdk.internal.le,jdk.internal.ed,jdk.internal.opt \


But still,

The generated runtime/bin/java --show-modules includes the full list of jdk modules.


In the code:

JLinkBundlerHelper.ModuleHelper ignores the limitMods argument and produces
a complete set of redistributable modules.


It should be possible to build a runtime with only the java.base module.

What should I expect?

Thanks, Roger

This refresh renames the packages used to jdk.jpackager and jdk.jpackager.runtime, removes the JNLPConverter demo, adds an initial set of automated tests, and contains fixes to the following issues:

JDK-8213324 jpackager deletes existing app directory without warning
JDK-8213166 jpackager --argument arg is broken
JDK-8213163 --app-image arg does not work creating exe installers
JDK-8212089 Prepare packager for localization
JDK-8212537 Create method and class description comments for main functionality
JDK-8213332 Create minimal automated tests for jpackager
JDK-8213333 Fix issues found in jpackager with automated tests
JDK-8213394 Stop using Log.info() except for expected output.
JDK-8213345 Secondary Launchers broken on mac.
JDK-8213156 rename packages for jpackager
JDK-8213244 Fix all warnings in jpackager java code
JDK-8212143 Remove native code that supports UserJvmOptionsService

The following additional issues are targeted to be address in the next few weeks:
JDK-8212936     Makefile and other improvements for jpackager
JDK-8212164     resolve jre.list and jre.module.list
JDK-8213392     Enhance --help and --version
JDK-8208652     File name is not passed to main() via file association on OS X
