我尝试运行mvn release：prepare（当然，发布后：clean），我收到错误：
无法执行目标org.apache.maven.plugins：maven-release-plugin：2.5：prepare（default-cli）...：编写POM时出错：D：\\ pom.xml（Access是拒绝）
引起：java.io.FileNotFoundException：D：... \ pom.xml（访问被拒绝）
问题：文件位于指定位置，但它是写保护的（因为它在SCM下）。所有的poms必须签到，否则我会在早期阶段（check-poms阶段）收到错误。所以pom必须签入，即写保护，因此我得到了＃34;访问被拒绝＆＃34;例外，它没有任何意义！
在下载了maven源码scm-plugin和release-plugin之后，我试图找到一些东西，但遗憾的是找不到这个异常的原因。也许我错过了一些东西，所以我在这里张贴，也许有人可以解释一下。
我已经在代码中的几个点添加了日志（在DefaultReleaseManager中，所以我可以看到相位），重新构建并且我看到它在相位上失败，称为＆＃39; rewrite-poms -for-release ＆＃39;，这是maven尝试将我的poms改为发布的阶段，并再次检查它们。但问题是这些poms受源代码控制，所以它们只读。所以插件无法写入这些poms，因此它会返回错误＆＃39; access denied＆＃39;。
试图查看相关课程中是否有某些内容class RewritePomsForReleasePhase extends AbstractRewritePomsPhase，但一无所获。试图用-X运行它，所以我得到了相关的例外（见下文）。
我使用maven-release-plugin：2.5，maven-scm-plugin：1.9，提供者是TFS（但是我不知道它与我的错误有什么关系，因为它没有在＆＃39中失败;提供者＆＃39;或在scm-plugin中。）
更新：
尝试使用maven-release-plugin重现：2.1，我知道这肯定有效（使用maven-scm：1.4）。我犯了同样的错误。所以我想我的配置中的某些内容是不正确的......也许这里有专家可以提供帮助吗？也许它与maven-scm-plugin有关？

答案 0 :(得分：0)
它似乎是maven-scm-provider-tfs中的一个错误。这意味着，对maven-scm-plugin的TFS支持并不完整。
我为此打开了JIRA item [SCM-752]，并建议修复。它将在maven-scm-plugin的下一个版本（1.10）中发布。
