Howdy,
Our projects are a mixture of cpp and java and I'd love to use maven just
like I have in the past for purely java project.
Consequently, Im trying to use the maven-native plugin but I am struggling!
So any help would be great!
First up I've installed cygwin and the gcc compiler. My goal is to produce
an .exe. I have created my maven project as follows:
*./pom.xml*
<project>
<modelVersion>4.0.0</modelVersion>
<groupId>debug</groupId>
<artifactId>helloworld-cpp</artifactId>
<version>1.0-SNAPSHOT</version>
<name>helloworld-cpp</name>
<packaging>exe</packaging>
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>native-maven-plugin</artifactId>
<extensions>true</extensions>
<configuration>
<sources>
<source>
<directory>./src/main/cpp</directory>
<includes>
<include>*.cpp</include>
</includes>
</source>
</sources>
<compilerProvider>generic-classic</compilerProvider>
<compilerExecutable>gcc</compilerExecutable>
</configuration>
</plugin>
</plugins>
</build>
</project>
*./src/main/cpp/HelloWorld.cpp*
#include <iostream>
using namespace std;
int main()
{
cout << "Hello world" << endl;
}
Thats it!
When I try and build the project I get the following error... which
unfortunately means nothing to me.
$ mvn install
