Maven：无法安装第 3 方 jar

Question

尝试将第 3 方 jar 安装到我的存储库 (alfresco-repository.jar) 中。我正在使用以下命令：

mvn install:install-file -DgroupId=alfresco -DartifactId=alfresco -Dversion=3.1 -Dpackaging=jar "-Dfile=C:/Users/xxx/Development/WIP/Alfresco/common/jars/alfresco/3.1/lib/alfresco-repository-3.1.jar" -DgeneratePom=true -e

我得到以下异常（-e 用于更多信息）：

[INFO] Scanning for projects...

问题是您在错误的地方使用了双引号 (")，有时根本没有。您应该在所有参数值周围使用双引号。例如...

"-Dfile=C:/Users/xxx/Development/WIP/Alfresco/common/jars/alfresco/3.1/lib/alfresco-repository-3.1.jar"

...应该是...

-Dfile="C:/Users/xxx/Development/WIP/Alfresco/common/jars/alfresco/3.1/lib/alfresco-repository-3.1.jar"

...和...

-Dversion=3.1

...应该是...

-Dversion="3.1"

不同操作系统的不同命令行会不一致地处理第一个版本，但如果您只用双引号将每个参数的 value 括起来，您每次都会得到所需的行为。你的整个命令应该是这样的......

mvn install:install-file -DgroupId="alfresco" -DartifactId="alfresco" -Dversion="3.1" -Dpackaging="jar" -Dfile="C:/Users/xxx/Development/WIP/Alfresco/common/jars/alfresco/3.1/lib/alfresco-repository-3.1.jar" -DgeneratePom="true" -e

我承认并不是所有人都需要这样做，但这是一个好习惯。
