Cannot load pcap4j-packetfactory-static on JavaFx project

[spencerwooo]

I'm running pcap4j with Java 12, on a JavaFX project using maven. I can run the project with javafx:run, but I can't load the pcap4j-packetfactory-static library. It seems that the module name static is a Java keyword and it can't be recognized during runtime. Is there something I'm doing wrong?

BTW, my pom.xml looks like this:

<dependencies>
    <dependency>
        <groupId>org.openjfx</groupId>
        <artifactId>javafx-controls</artifactId>
        <version>11.0.2</version>
    </dependency>
    <dependency>
        <groupId>org.openjfx</groupId>
        <artifactId>javafx-fxml</artifactId>
        <version>11.0.2</version>
    </dependency>
    <dependency>
        <groupId>org.pcap4j</groupId>
        <artifactId>pcap4j-core</artifactId>
        <version>2.0.0-alpha.3</version>
    </dependency>
    <dependency>
        <groupId>org.pcap4j</groupId>
        <artifactId>pcap4j-packetfactory-static</artifactId>
        <version>2.0.0-alpha.3</version>
    </dependency>
</dependencies>

That error should be solved by PR #207 which was merged very recently.
I will release a version with the fix within 2 weeks.
In the meantime, you can try a snapshot version: https://oss.sonatype.org/content/repositories/snapshots/org/pcap4j/pcap4j/2.0.0-alpha.4-SNAPSHOT/pcap4j-2.0.0-alpha.4-20190430.080233-9-distribution.zip

Thank you so much @kaitoy , I'll be trying the snapshot version asap.

Totally solved the problem! The snapshot version works like a charm. 🍻

For those who are also trying to use the snapshot version, here're my configurations:

• First modify your global maven repo settings in settings.xml, usually located at ~/.m2/settings.xml (Create a new one if you don't see it), then add <profiles> section in said file, like so:

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0">
    ...
    <profiles>
        <profile>
            <id>allow-snapshots</id>
            <activation><activeByDefault>true</activeByDefault></activation>
            <repositories>
                <repository>
                    <id>snapshots-repo</id>
                    <url>https://oss.sonatype.org/content/repositories/snapshots</url>
                    <releases><enabled>false</enabled></releases>
                    <snapshots><enabled>true</enabled></snapshots>
                </repository>
            </repositories>
        </profile>
    </profiles>
    ....
</settings>

• Then in your project's pom.xml file, change pcap4j's version to:

<dependency>
    <groupId>org.pcap4j</groupId>
    <artifactId>pcap4j-core</artifactId>
    <version>2.0.0-alpha.4-SNAPSHOT</version>
</dependency>
<dependency>
    <groupId>org.pcap4j</groupId>
    <artifactId>pcap4j-packetfactory-static</artifactId>
    <version>2.0.0-alpha.4-SNAPSHOT</version>
</dependency>

• Finally, run maven clean and maven install, and you're good to go.

Pcap4J 1.8.0 and 2.0.0-alpha.4 are released with Java 9+ support that includes fixes for this issue.
