Trying to come up with a minimal example I am having the maven-resolver-ant-tasks-1.6.0-uber.jar in a folder lib Additonally in the lib folder this POM minimal-example.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>org.example</groupId> <artifactId>Test</artifactId> <version>1.2.3-SNAPSHOT</version> <packaging>jar</packaging> <licenses> <license> <name>LGPL</name> <url>https://www.gnu.org/licenses/lgpl-3.0.de.html</url> </license> </licenses> <repositories> <repository> <name>Central Portal Snapshots</name> <id>central-portal-snapshots</id> <url>https://central.sonatype.com/repository/maven-snapshots/</url> <releases> <enabled>false</enabled> </releases> <snapshots> <enabled>true</enabled> </snapshots> </repository> </repositories> <description>Example POM</description> </project> ``` a build file ``` <?xml version="1.0" encoding="UTF-8"?> <project basedir="." default="deploy-maven" xmlns:resolver="antlib:org.apache.maven.resolver.ant"> <path id="maven.path"> <fileset dir="lib"> <include name="maven-resolver-ant-tasks-1.6.0-uber.jar" /> </fileset> </path> <!-- define the maven resolver ant tasks types and tasks --> <!-- Added typedefs so Ant can locate and load the antlib definitions from the provided jar --> <typedef resource="org/apache/maven/resolver/ant/antlib.xml" uri="antlib:org.apache.maven.resolver.ant" classpathref="maven.path" /> <target name="deploy-maven" description="deploy snapshot version to Maven snapshot repository (build jars only, skip javadoc/deploy zips)"> <property name="ossrh-snapshots-repository-url" value="https://central.sonatype.com/repository/maven-snapshots/"; /> <property name="ossrh-staging-repository-url" value="https://ossrh-staging-api.central.sonatype.com"; /> <!-- there server id in the Maven settings.xml --> <property name="ossrh-server-id" value="ossrh" /> <property name="jar.libs" value="lib/maven-resolver-ant-tasks-1.6.0-uber.jar" /> <resolver:deploy> <resolver:artifact file="${jar.libs}"> <resolver:pom file="lib/minimal-example.pom" /> </resolver:artifact> <resolver:snapshotrepo refid="Snapshots"/> </resolver:deploy> </target> </project> ``` Running it results in ``` C:\Users\dirks>ant -f minimal-example.xml deploy-maven Buildfile: C:\Users\dirks\minimal-example.xml deploy-maven: BUILD FAILED C:\Users\dirks\minimal-example.xml:30: java.lang.NullPointerException at org.apache.maven.resolver.internal.ant.tasks.AbstractDistTask.validateArtifactGav(AbstractDistTask.java:133) at org.apache.maven.resolver.internal.ant.tasks.AbstractDistTask.validate(AbstractDistTask.java:92) at org.apache.maven.resolver.internal.ant.tasks.Deploy.validate(Deploy.java:103) at org.apache.maven.resolver.internal.ant.tasks.Deploy.execute(Deploy.java:268) at org.apache.tools.ant.UnknownElement.execute(UnknownElement.java:299) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at org.apache.tools.ant.dispatch.DispatchUtils.execute(DispatchUtils.java:99) at org.apache.tools.ant.Task.perform(Task.java:350) at org.apache.tools.ant.Target.execute(Target.java:449) at org.apache.tools.ant.Target.performTasks(Target.java:470) at org.apache.tools.ant.Project.executeSortedTargets(Project.java:1401) at org.apache.tools.ant.Project.executeTarget(Project.java:1374) at org.apache.tools.ant.helper.DefaultExecutor.executeTargets(DefaultExecutor.java:41) at org.apache.tools.ant.Project.executeTargets(Project.java:1264) at org.apache.tools.ant.Main.runBuild(Main.java:818) at org.apache.tools.ant.Main.startAnt(Main.java:223) at org.apache.tools.ant.launch.Launcher.run(Launcher.java:284) at org.apache.tools.ant.launch.Launcher.main(Launcher.java:101) Total time: 0 seconds ``` However, if I put the POM one level up in the XML hierachy, i.e. outside the deploy-call, I do not get that error. It took me a while to figure out that this error happens because there MUST be a project-wide POM. The NPE was not helpful. Hence, I am asking to check to provide a message hinting to that. I am trying to deploy multiple artifacts, so I would prefer to have it nested. However, this is not subject to this request. -- This is an automated message from the Apache Git Service.
