Run example using Maven, no IDE required

[mattys101]

I noticed you mentioned that the current stuff can only be run using the IDE. You could set up an execution target in Maven so that you can run it easily without the IDE. If you want to that is. The code I use is below ;-)

<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>exec-maven-plugin</artifactId>
    <version>1.6.0</version>
    <configuration>
        <executable>java></executable>
        <mainClass>st.redline.Stic</mainClass>
        <arguments>
            <argument>st.redline.example.Test</argument>
        </arguments>
    </configuration>
</plugin>

The only problem with this, is you need to make your classpath handling more robust since Maven modifies the classpath at runtime, rather than specifying java.class.path variable.

Here's my hacky change to Stic's classPaths() method:

public String[] classPaths() {
    String[] classPaths = classPath().split(File.pathSeparator);

    ArrayList<String> urlClassPaths = new ArrayList<>(java.util.Arrays.asList(classPaths));
    URLClassLoader cl = (URLClassLoader) (Thread.currentThread().getContextClassLoader());
    for (URL url : cl.getURLs()) {
        if ("file".equals(url.getProtocol())) {
            urlClassPaths.add(url.getFile());
        }
    }

    classPaths = urlClassPaths.toArray(classPaths);

    return classPaths;
}

Cheers,

Matt

Redline must find a Smalltalk file in the classpath or in a JAR. This also enables Redline to be run from the command line.

You can run Redline from the command line with the following command to run Test.st

java -cp redline-0.6-SNAPSHOT.jar -jar redline-0.6-SNAPSHOT.jar st.redline.example.Test

NOTE

When compiling with Maven (mvn clean package) the resulting JAR is in the target folder, including the Smalltalk sources so the following shorter command line also works.

java -jar target/redline-0.6-SNAPSHOT.jar st.redline.example.Test
