Hi On a multi-module project, I have the ant:ant goal working fine. However, on a much simpler project based on the simples archetype, I get a ClassCast exception. Has anyone had/solved this issue before?
Thanks! Gary Stack trace and POM file below java.lang.ClassCastException: java.util.HashMap cannot be cast to java.lang.String at org.apache.maven.plugin.ant.AntBuildWriterUtil.getMavenPluginBasicOption( AntBuildWriterUtil.java:902) at org.apache.maven.plugin.ant.AntBuildWriterUtil.getMavenJarPluginBasicOption( AntBuildWriterUtil.java:838) at org.apache.maven.plugin.ant.AntBuildWriterUtil.writeJarTask( AntBuildWriterUtil.java:572) at org.apache.maven.plugin.ant.AntBuildWriter.writePackageTarget( AntBuildWriter.java:909) at org.apache.maven.plugin.ant.AntBuildWriter.writeGeneratedBuildXml (AntBuildWriter.java:304) at org.apache.maven.plugin.ant.AntBuildWriter.writeBuildXmls( AntBuildWriter.java:112) at org.apache.maven.plugin.ant.AntMojo.execute(AntMojo.java:112) at org.apache.maven.plugin.DefaultPluginManager.executeMojo( DefaultPluginManager.java:443) at org.apache.maven.lifecycle.DefaultLifecycleExecutor.executeGoals( DefaultLifecycleExecutor.java:539) at org.apache.maven.lifecycle.DefaultLifecycleExecutor.executeStandaloneGoal( DefaultLifecycleExecutor.java:493) at org.apache.maven.lifecycle.DefaultLifecycleExecutor.executeGoal( DefaultLifecycleExecutor.java:463) at org.apache.maven.lifecycle.DefaultLifecycleExecutor.executeGoalAndHandleFailures (DefaultLifecycleExecutor.java:311) at org.apache.maven.lifecycle.DefaultLifecycleExecutor.executeTaskSegments( DefaultLifecycleExecutor.java:278) at org.apache.maven.lifecycle.DefaultLifecycleExecutor.execute( DefaultLifecycleExecutor.java:143) at org.apache.maven.DefaultMaven.doExecute(DefaultMaven.java:334) at org.apache.maven.DefaultMaven.execute(DefaultMaven.java:125) at org.apache.maven.cli.MavenCli.main(MavenCli.java:280) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke( NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke( DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.codehaus.classworlds.Launcher.launchEnhanced(Launcher.java :315) at org.codehaus.classworlds.Launcher.launch(Launcher.java:255) at org.codehaus.classworlds.Launcher.mainWithExitCode(Launcher.java :430) at org.codehaus.classworlds.Launcher.main(Launcher.java:375) POM <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/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.elgaz.smart</groupId> <artifactId>demo-app</artifactId> <packaging>jar</packaging> <version>1.0-SNAPSHOT</version> <name>demo-app</name> <url>http://maven.apache.org</url> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>3.8.1</version> <scope>test</scope> </dependency> </dependencies> <build> <plugins> <plugin> <artifactId>maven-jar-plugin</artifactId> <configuration> <archive> <manifest> <addDefaultSpecificationEntries>true</addDefaultSpecificationEntries> <addDefaultImplementationEntries>true</addDefaultImplementationEntries> </manifest> </archive> </configuration> </plugin> <plugin> <artifactId>maven-assembly-plugin</artifactId> <configuration> <descriptorRefs> <descriptorRef>bin</descriptorRef> </descriptorRefs> </configuration> <executions> <execution> <goals> <goal>attached</goal> </goals> <phase>package</phase> </execution> </executions> </plugin> <plugin> <groupId>org.jvnet.jaxb2.maven2</groupId> <artifactId>maven-jaxb2-plugin</artifactId> <executions> <execution> <goals> <goal>generate</goal> </goals> </execution> </executions> <configuration> <generatePackage>com.demo.address</generatePackage> </configuration> </plugin> <plugin> <inherited>true</inherited> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <configuration> <source>1.5</source> <target>1.5</target> </configuration> </plugin> <plugin> <artifactId>maven-antrun-plugin</artifactId> <executions> <execution> <phase>package</phase> <goals> <goal>run</goal> </goals> <configuration> <tasks> <echo>ANT IS RUNNING!!!</echo> </tasks> </configuration> </execution> </executions> </plugin> </plugins> </build> <reporting> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-surefire-report-plugin</artifactId> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-checkstyle-plugin</artifactId> </plugin> </plugins> </reporting> <pluginRepositories> <pluginRepository> <id>maven2-repository.dev.java.net </id> <name>Java.net Maven 2 Repository</name> <url> http://download.java.net/maven/2</url> </pluginRepository> </pluginRepositories> </project>
