maven-2 - 如何手动将 jar 安装到本地 Maven 存储库？

Question

我想使用Google's GXP library在我的 Maven 项目中。我是 Maven 新手，并且遇到了很多麻烦，因为 .jar 在 Maven 存储库中已经不可用。根据我所读到的内容，我应该能够在本地存储库中安装该 jar，然后使用它。然而，我遇到了一些麻烦。有人知道我哪里出了问题吗？

PS C:\Documents and Settings\bmccann\Desktop> mvn install:install-file -Dfile=gxp-0.2.4-beta.jar -DgroupId=com.google -DartifactId=gxp -Dversion=0.2.4-BETA -Dpackaging=jar[INFO] Scanning for projects...[INFO] Searching repository for plugin with prefix: 'install'.[INFO] ------------------------------------------------------------------------[ERROR] BUILD FAILURE[INFO] ------------------------------------------------------------------------[INFO] Invalid task '.2.4-beta.jar': you must specify a valid lifecycle phase, or a goal in the format plugin:goal or pluginGroupId:pluginArtifactId:pluginVersion:goal[INFO] ------------------------------------------------------------------------[INFO] For more information, run Maven with the -e switch[INFO] ------------------------------------------------------------------------[INFO] Total time:

您使用的命令没问题。我刚刚复制并粘贴了它，并在我的本地存储库中成功安装了相同的新下载的 jar:

pascal@laptop:~/Downloads$ mvn install:install-file -Dfile=gxp-0.2.4-beta.jar -DgroupId=com.google -DartifactId=gxp -Dversion=0.2.4-BETA -Dpackaging=jar[INFO] Scanning for projects...[INFO] Searching repository for plugin with prefix: 'install'.[INFO] ------------------------------------------------------------------------[INFO] Building Maven Default Project[INFO]    task-segment: [install:install-file] (aggregator-style)[INFO] ------------------------------------------------------------------------[INFO] [install:install-file {execution: default-cli}][INFO] Installing /home/pascal/Downloads/gxp-0.2.4-beta.jar to /home/pascal/.m2/repository/com/google/gxp/0.2.4-BETA/gxp-0.2.4-BETA.jar[INFO] ------------------------------------------------------------------------[INFO] BUILD SUCCESSFUL[INFO] ------------------------------------------------------------------------[INFO] Total time: 2 seconds[INFO] Finished at: Wed Dec 09 08:44:37 CET 2009[INFO] Final Memory: 3M/53M[INFO] ------------------------------------------------------------------------

所以你肯定对maven-install-plugin有问题。插件(可能在下载不完整后损坏)。删除~/.m2/repository/org/apache/maven/plugins/maven-install-plugin (或者 ~/.m2/repository/org/apache/maven 下的更多内容)并重试。
