我試圖構建一個Maven插件，它將連接&會話連接到Oracle XE DB。當執行自定義Maven插件時，所需的類缺少oracle/jdbc/OracleDriver
我的插件生成沒有錯誤，但是當我嘗試通過Maven執行它時，出現OracleDriver丟失的錯誤。

我的Maven知識是有限的，我的Java是相當生鏽的。
我不確定是否需要在插件的POM中放置ojdbc6的依賴項。它建立&沒有它安裝愉快。添加它不能解決我的問題。
我的Java是目前很簡單，只是想獲得它進行會談到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();
}
}
}
該插件的POM是：

這就是扔的POM錯誤是：

Maven確實建議http://cwiki.apache.org/confluence/display/MAVEN/PluginContainerException作爲一種可能的解決方案。不幸的是，這僅僅表明我的JAR可能是腐敗的。
由於ojdbc6.jar存儲在我們的Artifactory存儲庫中，沒有其他人遇到問題，我刪除了它&重新下載它，沒有任何改變，我不認爲這是我的問題。 ojdbc6 jar存在於我的\.m2\repository\com\oracle\ojdbc6\11.2.0.2.0文件夾中
是否像OracleDriver不在ojdbc6.jar中那樣簡單（而且我的笨蛋）？
謝謝你可以提供的任何幫助，
Peter。
一位同事做它爲我工作，但是，只有更換'後DriverManager.registerDriver（新一個OracleDriver（））; ''用'Class.forName（「oracle.jdbc.driver.OracleDriver」）;' 我遇到的問題是，它完全飛行在面對doco http://docs.oracle.com/cd /E11882_01/appdev.112/e13995/oracle/jdbc/OracleDriver.html，它表示使用Class.forName不適用於所有情況。 – 2014-09-19 04:25:50
