Im really new to Java, really sorry !
Using maven like this (see below), I have the following error: "Missing artifact org.apache.plc4x:plc4x-parent:pom:0.8.0-SNAPSHOT" <?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd";> <modelVersion>4.0.0</modelVersion> <groupId>org.noovelia.plc4xtest</groupId> <artifactId>plc4xtest</artifactId> <version>1</version> <name>plc4xtest</name> <!-- FIXME change it to the project's website --> <url>http://www.example.com</url> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <maven.compiler.source>11</maven.compiler.source> <maven.compiler.target>11</maven.compiler.target> </properties> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.11</version> <scope>test</scope> </dependency> <dependency> <groupId>org.apache.plc4x</groupId> <artifactId>plc4x-parent</artifactId> <version>0.8.0-SNAPSHOT</version> <type>pom</type> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-simple</artifactId> <version>1.7.30</version> </dependency> </dependencies> <build> <pluginManagement> <!-- lock down plugins versions to avoid using Maven defaults (may be moved to parent pom) --> <plugins> <!-- clean lifecycle, see https://maven.apache.org/ref/current/maven-core/lifecycles.html#clean_Lifecycle --> <plugin> <artifactId>maven-clean-plugin</artifactId> <version>3.1.0</version> </plugin> <!-- default lifecycle, jar packaging: see https://maven.apache.org/ref/current/maven-core/default-bindings.html#Plugin_bindings_for_jar_packaging --> <plugin> <artifactId>maven-resources-plugin</artifactId> <version>3.0.2</version> </plugin> <plugin> <artifactId>maven-compiler-plugin</artifactId> <version>3.8.0</version> </plugin> <plugin> <artifactId>maven-surefire-plugin</artifactId> <version>2.22.1</version> </plugin> <plugin> <artifactId>maven-jar-plugin</artifactId> <version>3.0.2</version> </plugin> <plugin> <artifactId>maven-install-plugin</artifactId> <version>2.5.2</version> </plugin> <plugin> <artifactId>maven-deploy-plugin</artifactId> <version>2.8.2</version> </plugin> <!-- site lifecycle, see https://maven.apache.org/ref/current/maven-core/lifecycles.html#site_Lifecycle --> <plugin> <artifactId>maven-site-plugin</artifactId> <version>3.7.1</version> </plugin> <plugin> <artifactId>maven-project-info-reports-plugin</artifactId> <version>3.0.0</version> </plugin> </plugins> </pluginManagement> </build> </project> Patrick Boisclair Analyste - Programmeur senior / Senior Analyst Programmer [cid:image5f52f2.PNG@9f2ad524.4c9e310e]<https://www.noovelia.com> 462, rue des Forges, Trois-Rivières (Québec) G9A 2H5 CANADA noovelia.com<https://www.noovelia.com> [cid:image587f80.PNG@0d05f877.4ab61e6b] "Veuillez noter ma nouvelle adresse courriel. / Please note my new email address." ________________________________ De : Ben Hutcheson <hutc...@apache.org> Envoyé : 4 décembre 2020 20:06 À : dev@plc4x.apache.org Objet : Re: ADS Driver: org.apache.plc4x.java.api.exceptions.PlcRuntimeException: java.util.concurrent.TimeoutException Hi Patrick, I'll offer some general PLC4X hints as I don't have any experience with the Beckoff specific stuff, in exchange for some documentation updates when you sort it out. ;) 1) Make sure you are using the latest 0.8-SNAPSHOT version and not version 0.7. 2) The line PlcReadResponse response = request.execute().get(); supports a timeout. PlcReadResponse response = request.execute().get(1000, TimeUnit.MILLISECONDS); otherwise it won't return if there is a timeout. 3) Does the error happen all the time? 4) Can you narrow down what line the error occurs? 5) Do you see any packets being sent using Wireshark?
