XML Attribute not "saved" in the pom.xml ---------------------------------------- Key: FORGE-2648 URL: https://issues.jboss.org/browse/FORGE-2648 Project: Forge Issue Type: Bug Components: Build Tools - Maven Affects Versions: 3.2.0.Final Reporter: Clement Escoffier Assignee: George Gastaldi Fix For: 3.2.1.Final I've an addon that generates a Maven plugin configuration for the maven-shade-plugin. This plugin configuration requires XML attributes: {code:xml} <transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer"> <resource>META-INF/services/io.vertx.core.spi.VerticleFactory</resource></transformer> </transformers> {code} I create a configuration object that should contain these attributes: {code:java} public static Configuration getShadeConfiguration() { PluginElement manifestTransformer = ConfigurationElementBuilder.create() .setName("transformer") .addAttribute("implementation", "org.apache.maven.plugins.shade.resource.ManifestResourceTransformer") .setText("<manifestEntries>" + "<Main-Class>io.vertx.core.Launcher</Main-Class>" + "<Main-Verticle>${verticle.main}</Main-Verticle>" + "</manifestEntries>"); PluginElement appendingTransformer = ConfigurationElementBuilder.create() .setName("transformer") .addAttribute("implementation", "org.apache.maven.plugins.shade.resource.AppendingTransformer") .setText("<resource>META-INF/services/io.vertx.core.spi.VerticleFactory</resource>"); ConfigurationElement transformers = ConfigurationElementBuilder.create().setName("transformers") .addChild(manifestTransformer) .addChild(appendingTransformer); Configuration configuration = ConfigurationBuilder.create(); configuration.addConfigurationElement(ConfigurationElementBuilder.create().setName("outputFile").setText("${project" + ".build.directory}/${project.artifactId}-${project.version}-fat.jar")); configuration.addConfigurationElement(transformers); return configuration; } {code} But when this configuration is _persisted_ in the Maven `pom.xml` file, the attributes are missing. The rest of the metadata are present. For completeness here are how is configured the plugin: {code:java} builder.addExecution(ExecutionBuilder.create().addGoal("shade").setPhase("package").setId("package-fat-jar").setConfig(configuration)); pluginFacet.addPlugin(builder); {code} and in the `pom.xml` file I got only: {code:xml} <plugin> <artifactId>maven-shade-plugin</artifactId> <version>2.3</version> <executions> <execution> <id>package-fat-jar</id> <phase>package</phase> <goals> <goal>shade</goal> </goals> <configuration> <outputFile>${project.build.directory}/${project.artifactId}-${project.version}-fat.jar</outputFile> <transformers> <transformer> <manifestEntries> <Main-Class>io.vertx.core.Launcher</Main-Class> <Main-Verticle>${verticle.main}</Main-Verticle> </manifestEntries> </transformer> <transformer> <resource>META-INF/services/io.vertx.core.spi.VerticleFactory</resource> </transformer> </transformers> </configuration> </execution> </executions> </plugin> {code} It was working with Forge 2.20.1.Final.
