我试图构建一个Maven插件，它将连接&会话连接到Oracle XE DB。当执行自定义Maven插件时，所需的类缺少oracle/jdbc/OracleDriver
我的插件生成没有错误，但是当我尝试通过Maven执行它时，出现OracleDriver丢失的错误。

我的Maven知识是有限的，我的Java是相当生锈的。
我不确定是否需要在插件的POM中放置ojdbc6的依赖项。它建立&没有它安装愉快。添加它不能解决我的问题。
我的Java是目前很简单，只是想获得它进行会谈到Oracle：
package au.com.toll.toltat.script_import_maven_plugin;
import java.sql.DriverManager;
import java.sql.SQLException;
import oracle.jdbc.OracleDriver;
import org.apache.maven.plugin.AbstractMojo;
import org.apache.maven.plugin.MojoExecutionException;
import org.apache.maven.plugin.MojoFailureException;
/**
* Goal which imports Stored Procedure scripts
*
* @goal import
*
* @phase process-sources
*/
public class ScriptImportMojo extends AbstractMojo
{
/**
* Location of the file.
* @parameter property="sql.update.directory"
* @required
*/
private String inputUpdateDirectory;
/**
* Location of the file.
* @parameter property="sql.rollback.directory"
* @required
*/
private String inputRollbackDirectory;
public void execute()
throws MojoExecutionException, MojoFailureException
{
try {
// register our JDBC driver
DriverManager.registerDriver (new OracleDriver());
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
该插件的POM是：

这就是扔的POM错误是：

Maven确实建议http://cwiki.apache.org/confluence/display/MAVEN/PluginContainerException作为一种可能的解决方案。不幸的是，这仅仅表明我的JAR可能是腐败的。
由于ojdbc6.jar存储在我们的Artifactory存储库中，没有其他人遇到问题，我删除了它&重新下载它，没有任何改变，我不认为这是我的问题。 ojdbc6 jar存在于我的\.m2\repository\com\oracle\ojdbc6\11.2.0.2.0文件夹中
是否像OracleDriver不在ojdbc6.jar中那样简单（而且我的笨蛋）？
谢谢你可以提供的任何帮助，
Peter。
一位同事做它为我工作，但是，只有更换'后DriverManager.registerDriver（新一个OracleDriver（））; ''用'Class.forName（“oracle.jdbc.driver.OracleDriver”）;' 我遇到的问题是，它完全飞行在面对doco http://docs.oracle.com/cd /E11882_01/appdev.112/e13995/oracle/jdbc/OracleDriver.html，它表示使用Class.forName不适用于所有情况。 – 2014-09-19 04:25:50
