安装第三方JAR

Question

我在Eclipse中有一个名为TdkUtils的maven项目，带有以下pom.xml：这是一个utils项目。 因此，我想创建一个jar，将其放入存储库中，并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>
...

但是在安装插件时出现了以下错误：

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

Answer 1

如果只是在与util pom.xml文件位于同一目录中执行mvn install ，则maven会将jar文件安装到用户的本地存储库中。

之后，同一用户可以从其他项目中使用jar文件。

Answer 2

您可以像这样不使用pom.xml将jar安装到本地存储库： mvn install:install-file -Dfile=target/tdkUtils-0.0.1-SNAPSHOT.jar -DgroupId=com.tdk -DartifactId=tdkUtils -Dversion=0.0.1-SNAPSHOT -Dpackaging=jar
