Maven 中的 ojdbc jar 问题

Question

我在Java8中开发了一个项目，在使用java8开发项目时，我在maven中安装了ojdbc jar。现在我正在将项目转换成java 7. 这样做时，我面临 pom.xml 中 ojdbc.jar 依赖的问题。它显示：

Missing artifact com.oracle:ojdbc7:jar:12.1.0

在 oracle 依赖项标记中。当我尝试运行 ojdbc jar 的 mvn 安装时，也会引发错误。

[ERROR] Failed to execute goal on project SlotBookingAvailability: Could not resolve dependencies for project org.logicInfo.oms:SlotBookingAvailability:war:0.0. 1-SNAPSHOT: Failure to find com.oracle:ojdbc7:jar:12.1.0 in https://repo.maven.a pache.org/maven2 was cached in the local repository, resolution will not be reat tempted until the update interval of central has elapsed or updates are forced.

有人可以帮我解决这个问题吗？

Answer 1

由于 Oracle 许可，

Oracle JDBC 驱动程序（ojdbc6.jar、ojdbc7.jar、ojdbc8.jar）未发布到 Maven 中央存储库。如果它在您必须在本地安装它之前工作（例如通过运行 mvn install:install-file）或使用了除 Maven Central 以外的存储库。

您需要从 Oracle 网站手动下载 ojdbc7 并同意 OTN 许可协议。理想情况下，您将下载 ojdbc7 JAR 以匹配您的 Oracle 数据库服务器版本 (SELECT * FROM v$version)。

Answer 2

我同意 karol Dowbecki 的回答
我给你更多的安装细节
从 oracle's website
下载 jar 将 ojdbc7.jar 添加到本地 maven 存储库。

打开命令window

运行命令：mvn install:install-file -DgroupId=com.oracle -DartifactId=ojdbc7 -Dversion=12.1.0 -Dpackaging=jar -Dfile=G:/Jar/ojdbc7.jar

将 jar 名称位置版本更改为您的

然后你会在你的maven本地仓库中找到jar，比如${mavenrepository}/com/oracle/ojdbc7/${yourversion}/

然后你可以在你的maven中使用你的设置pom.xml

Answer 3

请从 OTN or you can download these from Oracle Maven repository (maven.oracle.com). Refer to the blog 下载 Oracle JDBC 驱动程序以获取有关从 Oracle Maven 下载它的说明。
