安装 3rd 方 JAR

Question

我在 Eclipse 中有一个名为 TdkUtils 的 Maven 项目，其中 pom.xml：这是一个实用程序项目。所以我想创建一个jar，把它放在存储库中，然后在其他项目中使用它。

...
<groupId>com.tdk</groupId>
  <artifactId>tdkUtils</artifactId>
  <version>0.0.1-SNAPSHOT</version>
  <packaging>jar</packaging>

  <name>tdkUtils</name>
...

但是我在安装插件时遇到了这些错误：

MacBook-Pro-de-nunito:tdkUtils nunito$ mvn install:install-file -Dfile=target/tdkUtils-0.0.1-SNAPSHOT.jar

Answer 1

如果您只是在与 util pom.xml 文件相同的目录中执行 mvn install，maven 将为用户将 jar 文件安装到本地存储库中。

之后，jar 文件可以被其他项目的同一用户使用。

Answer 2

你可以在没有 pom.xml 的情况下将 jar 安装到本地 repo，如下所示： mvn install:install-file -Dfile=target/tdkUtils-0.0.1-SNAPSHOT.jar -DgroupId=com.tdk -DartifactId=tdkUtils -Dversion=0.0.1-SNAPSHOT -Dpackaging=jar
