Briefly, this error occurs when Elasticsearch is unable to access the Java classpath. This could be due to incorrect Java installation, incorrect environment variable settings, or insufficient permissions. To resolve this issue, you can verify your Java installation and ensure that the JAVA_HOME environment variable is correctly set. If the problem persists, check the permissions of the Elasticsearch installation directory. You may also need to check if the classpath is correctly defined in the Elasticsearch startup script.

    @Classpath
    public String getResourcesClasspath() {
        // This will make sure the task is not considered up to date if the resources are changed.
        logger.info("Classpath: {}"; System.getProperty("java.class.path"));
        return System.getProperty("java.class.path");
    }

    public void setOutputDir(File outputDir) {
        this.outputDir.set(outputDir);
