mvn release - 标记时出现 svn 错误

Question

在尝试执行 release:prepare 目标时，出现以下故障：

该项目在发布版本的主干中得到了很好的更新，但不在TAGS中，看起来它正在尝试做svn合并？！是吗？如果是，为什么？

这是 maven-release-plugin 配置：

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-release-plugin</artifactId>
            <version>2.5.3</version>
            <dependencies>
                <dependency>
                    <groupId>com.google.code.maven-scm-provider-svnjava</groupId>
                    <artifactId>maven-scm-provider-svnjava</artifactId>
                    <version>1.6</version>
                </dependency>
            </dependencies>
            <configuration>
                <providerImplementations>
                    <svn>javasvn</svn>

                <tagBase>https://192.19.20.56/svn/xxxxx/xxx-parent/TAGS</tagBase>
                <scmCommentPrefix>TT 00000: Tagging release of project ${project.name} ${project.version}, </scmCommentPrefix>
            </configuration>
        </plugin>

Answer 1

Maven 的输出包含指针：

[ERROR] svn: Commit failed (details follow):
[ERROR] svn: Commit blocked by pre-commit hook (exit code 1) with output:
[ERROR] A message is mandatory!
[ERROR] The message must comply to the following structure 'TT 12345: Some explanation'.
[ERROR] Pay attention to the white space between TT and the TT number and between the colon and the explanation.
[ERROR] The explanation after the colon should at least be 10 characters long.

您的团队安装了不允许此提交的预提交挂钩，因为缺少提交消息。我只能假设您包含的 maven-release-plugin 配置不是实际激活的配置，因为它不仅包含提交消息，还包含所需格式的配置：

<scmCommentPrefix>TT 00000: Tagging release of project ${project.name} ${project.version}, </scmCommentPrefix>

您可以像这样尝试 adding a commit message manually by using a command-line parameter：

mvn release:prepare -DscmCommentPrefix="TT 00000: Tagging release of project..."

我找到的解决方案是更改发布插件使用的maven-scm-provider-svnjava 的版本。原来用的是1.6版本，我改成1.15了，有了这个配置，我就可以准备发布了。

Subversion 存储库是 1.6 版，不确定我可以使用的最新版本的 maven-scm-provider-svnjava 是什么。
