Question

我对Maven感到不舒服，但我设法让它与Netbeans一起工作了一段时间。但突然间，Maven拒绝下载新的依赖项：

org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal on project matheos: Could not resolve dependencies for project lecoleopensource:matheos:jar:1.4.4-SNAPSHOT: The repository system is offline but the artifact org.docx4j:docx4j-ImportXHTML:jar:3.2.2 is not available in the local repository.

有些东西显然是离线的，但我不明白为什么以及如何解决这个问题。

这是我的pom文件的一部分：

    <dependencies>
        <!-- docx4j : converts html to docx -->
        <dependency>
                <groupId>org.docx4j</groupId>
                <artifactId>docx4j</artifactId>
                <version>3.2.2</version>
        </dependency>

        <!-- pdf2dom : converts pdf to html -->
        <!--dependency>
                <groupId>net.sf.cssbox</groupId>
                <artifactId>pdf2dom</artifactId>
                <version>1.3</version>
        </dependency-->


    </dependencies>

我不明白的是它以前一直工作得很好......

我不太了解Maven，所以告诉我是否应该提供其他细节。谢谢！

编辑：我删除了存储库部分，仍然相同。我将artefactID编辑为docx4j，仍然是相同的。

只需删除您定义的存储库部分即可。您既不需要定义本地存储库，因为它仍然在settings.xml Maven配置中定义，也不会将项目依赖项放在src / main / resources下。

<强>更新

你是否正在以“离线模式”运行Maven？看看你的Netbeans首选项 - ＆gt; Java - ＆gt; Maven和您的运行配置，如果有“-o”参数。

Maven没有下载依赖项：＆＃34;存储库系统处于脱机状态＆＃34;
