----------------------------------
Summary: Packaging fails when 'Automatic Modules' exist.
Key: MJMOD-7
URL: https://issues.apache.org/jira/browse/MJMOD-7
Project: Maven JMod Plugin
Issue Type: Bug
Affects Versions: 3.0.0-alpha-1
Environment: JDK 9+181, OS X 10.12.6, Maven 3.5.0
Reporter: Stephen Davies
Hi,
am new to JDK 9 and attempting to migrate an existing JNI project of mine,
https://sourceforge.net/projects/yad2xx/, to the new module format.
The current project is setup as a multi module project with separate submodules
for the JAR, DLL and JNILIB targets. The project targets Win7/8/10 and OS X but
I generally use OS X. The Java and native library are building ok.
The project has one compile/runtime dependency on Apache commons-cli. As far as
I am aware there is currently no JDK 9 module for commons-cli. I have watched
the video on JDK 9 Modular Development
(https://blogs.oracle.com/java/modular-development) and as far as I can tell it
should be relatively easy to make my code a module without requiring common-cli
to also be a module.
According to the video (~30min mark) my module can use the 'Automatic Modules'
feature and the JDK will infer a module from the commons-cli JAR. I am using
following module-info.java file:
module net.sf.yad2xx {
requires java.base;
requires commons.cli;
exports net.sf.yad2xx;
}
The Maven compile phase succeeds with this warning:
[WARNING]
********************************************************************************************************************
[WARNING] * Required filename-based automodules detected. Please don't publish
this project to a public artifact repository! *
[WARNING]
********************************************************************************************************************
Unfortunately, the process fails at the package phase:
[ERROR] Failed to execute goal
org.apache.maven.plugins:maven-jmod-plugin:3.0.0-alpha-1:create
(default-create) on project yad2xx:
[ERROR] Exit code: 2
[ERROR] Command line was: /bin/sh -c
/Library/Java/JavaVirtualMachines/jdk-9.jdk/Contents/Home/bin/jmod
@/Users/sjdavies/workspace_oxy1a/yad2xx/target/jmodCreateArgs
I suspect the contents of jmodCreateArgs is the problem:
create
--module-version
1.1-SNAPSHOT
--class-path
/Users/sjdavies/workspace_oxy1a/yad2xx/target/classes:/Users/sjdavies/.m2/repository/commons-cli/commons-cli/1.4/commons-cli-1.4.jar

/Users/sjdavies/workspace_oxy1a/yad2xx/target/jmods/yad2xx.jmod
Should the tool be putting the JAR file on the --module-path?
