I have fixed this issue by deleting local .m2/repositoryfolder. The build is successful now.

我通过删除本地.m2/repository文件夹解决了这个问题。现在构建成功。

recently I stuck with the same problem. I turns that assembly-plugin doesn't propagate/report errors with dependencies:

最近我遇到了同样的问题。我认为 assembly-plugin 不会传播/报告具有依赖项的错误：

[DEBUG] Resolving project dependencies transitively.
[DEBUG] com.g.....0.4-SNAPSHOT (selected for null)
[DEBUG]           org.springframework:spring-expression:jar:3.1.4.RELEASE:compile (selected for compile)
[DEBUG]           org.springframework:spring-asm:jar:3.1.4.RELEASE:compile (selected for compile)
[DEBUG]         trove:trove:jar:1.0.2:compile (selected for compile)
[INFO] ------------------------------------------------------------------------

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-assembly-plugin:2.5.4:single (full) on project p...o: Execution full of goal org.apache.maven.plugins:maven-assembly-plugin:2.5.4:single failed: For artifact {null:null:null:jar}: The groupId cannot be empty. -> [Help 1]

that's all what I've got from assembly-plugin. eg. compiler warns about the broken stuff:

这就是我从程序集插件中得到的。例如。编译器警告损坏的东西：

[WARNING] error reading /var/lib/jenkins/...org/hyperic/sigar/1.6.3.82/sigar-1.6.3.82.jar; error in opening zip file
[WARNING] error reading /var/lib/jenkins/.../org/hyperic/sigar/1.6.3.82/sigar-1.6.3.82.jar; error in opening zip file

Thus, if you've been stuck in this trouble, invoke mvn dependency:treeto troubleshoot the dependency.

因此，如果您一直被困在这个麻烦中，请调用mvn dependency:tree以解决依赖关系。

And mine has a different solution. I had a POM that had a <dependencyManagement>entry for the jar withoutany <version>, andit had a <dependencies>entry for the jar witha <version>. Plus, the parent POM had a <dependencyManagement>entry withthe same <version>. Apparently this confused Maven (3.3). The build worked fine, but the packaging did not.

我有一个不同的解决方案。我有一个POM是有一个<dependencyManagement>对JAR条目没有任何<version>，和它有一个<dependencies>对JAR条目有一个<version>。另外，父POM有一个<dependencyManagement>条目与相同<version>。显然这让 Maven (3.3) 感到困惑。构建工作正常，但包装没有。

Fix: remove <dependencyManagement>entry in the child POM, and remove the <version>from the <dependencies>entry in the child POM.

修复：删除<dependencyManagement>子 POM中的条目，并<version>从<dependencies>子 POM 中的条目中删除。

In code, here is the broken situation:

在代码中，这是损坏的情况：

Parent pom.xml:
<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.apache.httpcomponents</groupId>
            <artifactId>httpclient</artifactId>
            <version>${httpclient.version}</version>
        </dependency>
    </dependencies>
</dependencyManagement>

Child pom.xml:
<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.apache.httpcomponents</groupId>
            <artifactId>httpclient</artifactId>
        </dependency>
    </dependencies>
</dependencyManagement>
...
<dependencies>
    <dependency>
        <groupId>org.apache.httpcomponents</groupId>
        <artifactId>httpclient</artifactId>
        <version>${httpclient.version}</version>
    </dependency>
</dependencies>

Post fix: parent POM is the same, child pom has just this

后修复：父 POM 是相同的，子 POM 只有这个

<dependencies>
    <dependency>
        <groupId>org.apache.httpcomponents</groupId>
        <artifactId>httpclient</artifactId>
    </dependency>
</dependencies>

If you look at your maven build output, there should be some warnings that say .pom is invalid, transitive dependencies (if any) will not be available. Delete all the artifacts corresponding to those poms and rebuild, you need not delete the entire repository.

如果你查看你的 maven 构建输出，应该会有一些警告说 .pom 无效，传递依赖（如果有）将不可用。删除与这些 poms 对应的所有工件并重建，您不需要删除整个存储库。

I recently came across this building a spring boot 2.2 project. Turns out the problem was an out of date maven-assembly-plugin. Our build specified 2.3 but spring boot's bom requested at least 3.1.1. Bumping to 3.2.0 (the latest at time of writing) fixed the problem.

我最近遇到了这个构建 spring boot 2.2 项目的项目。原来问题是一个过时的 maven-assembly-plugin。我们的构建指定了 2.3，但 spring boot 的 bom 要求至少 3.1.1。撞到 3.2.0（撰写本文时的最新版本）修复了该问题。
