To: users@maven.apache.org, dev@maven.apache.org


Hello there,

I have a question regarding maven release plugin. We use codehaus
native-plugin to build jni, I want to pass the cflags during release phase.
However I see that I am unable to pass any of the arguments through release
plugin. Any experience or pointers would help
this is mvn command which we call through a makefile similar to
https://github.com/apache/incubator-mxnet/blob/
48d60908a1fa42364a829ac90133d28dd0998219/Makefile#L579
```
scalareleasedryrun:
(cd $(ROOTDIR)/scala-package; \
mvn -X release:prepare -DdryRun=true -DautoVersionSubmodules=true \
-P$(SCALA_PKG_PROFILE),$(SCALA_VERSION_PROFILE) \
-Darguments=-DskipTests -Dcxx="$(CXX)" \
-Drelease.cflags="$(CFLAGS)" -Dldflags="$(LDFLAGS)" \
-Dlddeps="$(LIB_DEP) $(ROOTDIR)/lib/libmxnet.a")
```
The parent pom file is here
https://github.com/apache/incubator-mxnet/blob/master/scala-package/pom.xml
and the pom file to compile native code is here https://github.com/apache/
incubator-mxnet/blob/master/scala-package/init-native/osx-x86_64/pom.xml#L59

I see that cflags variable used in the native pom.xml is coming as null

```

I have already tried pass with -Darguments, create properties corresponding
to the flags, etc.,


Appreciate pointers and advise?
