Question

我正在尝试构建一个Maven插件，它可以连接＆amp;与Oracle XE DB进行对话。

我的插件构建没有错误，但是当我尝试通过Maven执行它时，我得到错误，OracleDriver丢失了。

我的Maven知识有限，我的Java相当生疏。

我不确定是否需要在插件的POM中添加ojdbc6的依赖项。它建立和没有它安装愉快。添加它并不能解决我的问题。

我的JAVA目前非常简单，只是想让它与Oracle交流：

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();
        }
    }
}

插件的POM是：

Maven确实建议http://cwiki.apache.org/confluence/display/MAVEN/PluginContainerException作为可能的解决方案。不幸的是，这仅仅表明我的JAR可能已经腐败。

由于ojdbc6.jar存储在我们的Artifactory存储库中，并且没有其他人遇到问题，我已将其删除了。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

是否因为OracleDriver不在ojdbc6.jar中而变得简单（而且代表我很愚蠢）？

感谢您提供的任何帮助，

彼得。

Answer 1

将依赖项添加到当前失败的POM中的插件配置：

<build>
  <plugins>
    <plugin>
      <groupId>com.tollgroup.tollonline.deploy</groupId>
      <artifactId>script-import-maven-plugin</artifactId>
      <version>1.0-SNAPSHOT</version>
      <dependencies>
          <dependency>
              <groupId>com.oracle</groupId>
              <artifactId>ojdbc6</artifactId>
              <version>11.2.0.2.0</version>
          </dependency>
      </dependencies>
    </plugin>
  </plugins>
</build>

Answer 2

修正了......

我导入oracle.jdbc.OracleDriver;时，我应该导入import oracle.jdbc.driver.OracleDriver;。

两者都是有效的选项，但只有一个是正确的。： - （

还必须在插件POM中将ojdbc6的范围更改为runtime。

执行自定义Maven插件时，必需的类缺少oracle / jdbc / OracleDriver
