maven-版本插件:2.5:准备失败与“错误写入POM：(访问被拒绝)”

Question

我尝试运行mvn发行版:准备(当然，在发布后:clean)，我得到了一个错误：

org.apache.maven.plugins:maven-release-plugin:2.5:prepare (默认-cli).：错误写入POM: D:\pom.xml (访问被拒绝)

由: java.io.FileNotFoundException: D:...\pom.xml (访问被拒绝)引起

问题:该文件位于指定的位置，但它是写保护的(因为它在SCM下)。所有的poms必须签入，否则在早期阶段(签入阶段)会出现错误。因此pom必须签入，即写保护，因此我得到“访问拒绝”异常，这是没有任何意义的！

在下载了maven源代码( scm-plugin和release)之后，我试图找到一些东西，但不幸的是，我找不到出现这种异常的原因。也许我漏掉了什么东西，所以我把它发到这里，也许有人能给我一些启示。

我在代码中的几个点添加了日志(在DefaultReleaseManager中，这样我就可以看到阶段)，重新构建，并且我看到它在名为'rewrite-poms-for-release'，的阶段上失败，在这个阶段，maven试图将我的poms转换成发行版，并再次签入它们。但问题是，这些吊杆是在源代码控制下，所以它们是只读的。所以插件不能写到这些标签上，所以它返回错误“拒绝访问”。

试图查看相关类class RewritePomsForReleasePhase extends AbstractRewritePomsPhase中是否有什么东西，但什么也没有发现。尝试用-X运行它，所以我得到了相关的异常(参见下面)。

我使用maven-release:2.5，maven-scm-plugin:1.9，提供程序是TFS (但我不知道它与我的错误有什么关系，因为它不会在' provider‘或scm-plugin中失败)。

更新

只是尝试用maven-release:2.1进行复制，我知道它确实有效(使用maven-scm:1.4)。我也会犯同样的错误。所以我想我的配置是不正确的.也许这里有专家能帮上忙？也许它与maven-scm插件有关？

Answer 1

它似乎是maven-scm-provider-tfs中的一个bug。这意味着，TFS对maven-scm插件的支持还不够充分.

我已经为此打开了一个JIRA项目[SCM-752]，并建议进行修复。它将在maven-scm插件的下一个版本(1.10)中发布。
