【问题描述】：

我有一个使用多模块的 Maven 项目，当我执行命令 release:prepare 时，出现了一些问题：

[INFO] Working directory: C:\Java\workspace

[ERROR] BUILD FAILURE

            </plugin>
        </plugins>

</project>

如果我把标签 <remoteTagging>false</remoteTagging> ，另一个问题：

[INFO] Working directory: C:\Java\workspace
[INFO] ------------------------------------------------------------------------
[ERROR] BUILD FAILURE
[INFO] ------------------------------------------------------------------------
[INFO] Unable to tag SCM
Provider message:
The svn tag command failed.
Command output:
svn: E155007: 'C:\Java\workspace' is not a working copy

我的项目位于“C:\Java\workspace\logreport”中。

【问题讨论】：

这可能对 IME 没有帮助，如果您的项目有外部变量并且错误消息没有提供信息，则发布命令不起作用。你的项目中有 externs 吗？
你能否展示完整的文件夹结构，你是如何调用 maven 的，以及你从哪里调用了 maven 的命令？

标签： java maven release maven-plugin maven-release-plugin

【解决方案1】：

通常，如果您有一个多模块构建，您应该具有以下结构：

  +-- parent (pom.xml)
       +-- module-1 (pom.xml)
       +-- module-2 (pom.xml)

这意味着父节点也位于 VCS 的主干中（在本例中为 SVN）。

此外，上述结构的结果是你的父母看起来像这样：

<modelVersion>4.0.0</modelVersion>

<groupId>com.company.logreport</groupId>
<artifactId>parent</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>pom</packaging>

<modules>
    <module>logreport-client</module>
    <module>logreport-common</module>
    <module>logreport-server</module>
</modules>

而在父节点中只定义一次的scm信息如下：

<scm>
    <developerConnection>scm:svn:svn://[hidden]/svn/infra/trunk/</developerConnection>
    <connection>scm:svn:svn://[hidden]/svn/infra/trunk/</connection>
    <url>svn://[hidden]/svn/infra/trunk/</url>
</scm>

除此之外，您永远不应该在 pom.xml 中定义密码。这些东西的预定位置是settings.xml。

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
                      http://maven.apache.org/xsd/settings-1.0.0.xsd">
  ...
  <servers>
    <server>
      <id>svn-server</id>
      <username>my_login</username>
      <password>my_password</password>
    </server>
  </servers>
  ...
</settings>
