Anteater Troubleshooting Guide

Welcome to the Anteater troubleshooting guide! This page provides solutions and steps to resolve common issues encountered while using the Anteater tool. If you're facing specific problems, follow the steps below or consult related documentation.

Java Not Found or Installation Issues

Symptoms:

  • Error: 'java' is not recognized as an internal or external command...
  • Anteater executable (ae.jar, anteater.jar) fails to start.

Solution:

  1. Ensure Java is installed (minimum Java 8 or higher).
  2. Verify your Java installation: 
    java -version

    The output should display the Java version and runtime details.

  3. If Java is not installed:
  4. Check the JAVA_HOME environment variable:
    • Ensure it points to the Java installation directory.
    • Add Java's bin directory to the system's PATH.

Missing Anteater Files

Symptoms:

  • Error: anteater.jar not found in <directory>.
  • Plugin errors: Plugins folder not found.

Solution:

  1. Ensure the Anteater jar file is downloaded and present in the correct directory.
    • File: anteater.jar or ae.jar must exist in the same directory as the script or executable.
  2. Verify the plugins directory:
    • Ensure the directory exists and contains necessary plugins for your use case.
    • If absent, download or create a plugins folder as required.

Maven Plugin Issues

Symptoms:

  • Error: No plugin found for prefix 'ae'.
  • Deployment or execution failure when using Maven commands.

Solution:

  1. Ensure the Anteater Maven plugin is properly configured in your pom.xml file: 
    <build>
  <plugins>
    <plugin>
      <groupId>com.ganteater</groupId>
      <artifactId>ae-maven-plugin</artifactId>
      <version>1.2.3</version>
    </plugin>
  </plugins>
</build>

Check if the Required Maven Repository is Available

If you are using a snapshot version of the Anteater application, you need to ensure that Maven can resolve snapshot dependencies through properly configured repositories. You can update your settings.xml or add the required repository directly to your pom.xml.

Here’s how you can do that:

Option 1: Update Maven settings.xml

Configure your Maven settings.xml file to include the snapshot repository:

    <settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
              xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
              xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 https://maven.apache.org/xsd/settings-1.0.0.xsd">
        <profiles>
            <profile>
                <id>central-repositories</id>
                <activation>
                    <activeByDefault>true</activeByDefault>
                </activation>
                <repositories>
                    <repository>
                        <id>central-snapshots</id>
                        <url>https://central.sonatype.com/repository/maven-snapshots</url>
                        <releases><enabled>false</enabled></releases>
                        <snapshots><enabled>true</enabled></snapshots>
                    </repository>
                    <repository>
                        <id>central</id>
                        <url>https://repo1.maven.org/maven2/</url>
                        <releases><enabled>true</enabled></releases>
                        <snapshots><enabled>false</enabled></snapshots>
                    </repository>
                </repositories>

                <pluginRepositories>
                    <pluginRepository>
                        <id>plugin-snapshots</id>
                        <url>https://central.sonatype.com/repository/maven-snapshots</url>
                    </pluginRepository>
                </pluginRepositories>
            </profile>
        </profiles>
    </settings>

With this configuration, Maven will resolve snapshot dependencies from the Sonatype snapshot repository when needed.

Option 2: Add Repositories to pom.xml

If modifying the settings.xml file is not feasible, you can instead add the required repositories directly to your project’s pom.xml.

Include the following configuration under the <repositories> section of your pom.xml:

<repositories>
    <repository>
        <id>central-snapshots</id>
        <url>https://central.sonatype.com/repository/maven-snapshots</url>
        <releases>
            <enabled>false</enabled> <!-- Disable releases for snapshots -->
        </releases>
        <snapshots>
            <enabled>true</enabled> <!-- Enable snapshots -->
        </snapshots>
    </repository>
    <repository>
        <id>central</id>
        <url>https://repo1.maven.org/maven2/</url>
        <releases>
            <enabled>true</enabled> <!-- Enable releases -->
        </releases>
        <snapshots>
            <enabled>false</enabled> <!-- Disable snapshots -->
        </snapshots>
    </repository>
</repositories>

<pluginRepositories>
    <pluginRepository>
        <id>plugin-snapshots</id>
        <url>https://central.sonatype.com/repository/maven-snapshots</url>
    </pluginRepository>
</pluginRepositories>

Key Notes:

  1. Snapshots: A snapshot version is a development build and frequently updated. Snapshots are typically denoted with a version like 1.2.3-SNAPSHOT.
  2. Releases: Regular released versions are considered stable (e.g., 1.2.3).
  3. Why the Configuration is Necessary:
    • Snapshot dependencies are only available in snapshot repositories, such as https://central.sonatype.com/repository/maven-snapshots.
    • Released dependencies (non-snapshots) are available in Maven Central (https://repo1.maven.org/maven2/).

This ensures Maven can properly resolve and download snapshot dependencies for the Anteater application or other tools hosted in the Sonatype snapshot repository.

  1. Refresh Maven dependencies: 
    mvn clean install -U
  2. If errors persist:
    • Fully qualify the plugin execution: 
      mvn com.ganteater:ae-maven-plugin:run

Configuration Issues

Symptoms:

  • Error messages during execution: Cannot find configuration file, Invalid classpath.
  • Misbehavior due to missing environment variables.
Solution:
  1. Ensure required configuration files (e.g., ae.xml) are placed in the correct directory.
  2. Verify necessary environment variables:
    • MAVEN_HOME: Points to Maven installation directory.
    • JAVA_HOME: Points to Java installation directory.
  3. Test environmental setup by running: 
    java -cp ae.jar com.ganteater.ae.desktop.Anteater
