Question

在我提出这个问题之前，我已经阅读了有关此问题的所有帖子，我可以在Stack Overflow上找到。

我在myven pom.xml中的classpath中定义了SQLite jdbc驱动，如下所示

    <!--  SQLite uploads -->
    <dependency>
        <groupId>org.xerial</groupId>
        <artifactId>sqlite-jdbc</artifactId>
        <version>3.8.7</version>
    </dependency>

错误堆栈跟踪：

Caused by: java.sql.SQLException: No suitable driver found for jdbc:sqlite:C:\Users\zk5426x\AppData\Local\Temp\cms8026785111405543526.db
    at java.sql.DriverManager.getConnection(DriverManager.java:689)
    at java.sql.DriverManager.getConnection(DriverManager.java:270)

我能够验证文件C:\Users\zk5426x\AppData\Local\Temp\cms8026785111405543526.db是否可写。

我的代码如下：

// Writing byte array to the db file.
public Set<CmsXServiceContent> readContentFromSqliteStream(byte[] bytes) throws Exception {
       Path path = null;
    try {
      path = Files.createTempFile("cms", ".db");
      if (LOGGER.isInfoEnabled()) {
        LOGGER.info("Temporary file created = " + path.toString());
      }
      try (ByteArrayInputStream is = new ByteArrayInputStream(bytes);) {
        Files.copy(is, path, StandardCopyOption.REPLACE_EXISTING);
        Class.forName("org.sqlite.JDBC");
      try(
        Connection conn =
            DriverManager.getConnection(
                 "jdbc:sqlite:" +  path.toFile().getCanonicalPath());) {

        // Prepared Statements and result set query.
        }
      }
    } catch (IOException e) {
      LOGGER.error("Unable to create a temporary file: cms.db");
      throw e;
    } finally {
      if (path != null) {
        path.toFile().deleteOnExit();
      }
    }
}

以下声明会生成错误。在此声明中C:\Users\zk5426x\AppData\Local\Temp\cms8026785111405543526.db是可写的。

Connection conn = DriverManager.getConnection("jdbc:sqlite:" + path.getFileName());

代码编译。我想弄清楚的是如何解决这个问题？我已经使用Maven将SQLite-jdbc jar添加到了我的类路径中。

（更新） Youcef Laidani建议我从.m2目录中删除二进制文件。执行此操作并执行mvn test命令后，我看到以下堆栈跟踪。
