Question

我有一个mavenized构建（maven3），它有一个加载mySQL数据库转储的模块。这在Windows下可以正常工作，但在Linux下则不行。

使用-X开关运行maven，它会生成以下输出：

[DEBUG] Using mysql at /usr/bin/mysql
[DEBUG] Command to execute: mysql -uMYUSER --password=**** -hlocalhost --quick --max_allowed_packet=16M --default-character-set=utf8 -e "source /this/path/to/my/database/dump/is/longer/than/70/characters/the_dump.sql"
[ERROR] ERROR 1102 (42000): Incorrect database name '/this/path/to/my/database/dump/is/longer/than/70/characters/the_dump.'

如果我直接在命令行上运行调试输出，则the_dump.sql脚本可以正常工作。我的猜测是Maven没有正确识别参数和/或截断它们（注意第二个参数在错误消息中被截断为70个字符）。我无法承受在Windows下构建失败的原因 - 由于数据库脚本中的某些命令，它无法通过将其传递到带有“＆lt;”的mysql来正确运行管。

以下是相关的pom片段：

来自db-dumps-maven-plugin的执行片段：

@Override
public void execute() throws MojoExecutionException {

    final Set<String> dumpsToInsertLowerCase = evaluateDumpsToInsert();

    final List<File> sqlFiles = findFiles(folderWithDumps, ".sql", dumpsToInsertLowerCase);
    getLog().info("Inserting dumps: " + sqlFiles);

    for (final File sqlFile : sqlFiles) {
        String createCommand = "mysql -u%s --password=%s -h%s --quick --max_allowed_packet=16M --default-character-set=utf8 -e \"source %s\"";
        Object[] createArgs = {username, password, hostname, sqlFile.getAbsolutePath().replace("\\", "/")};
        executeCommand(createCommand, createArgs);
    }
}

public void executeCommand(final String command, final Object[] arguments) {

    final String commandToExecute = String.format(command, arguments);
    mavenPlugin.getLog().debug("Command to execute: " + commandToExecute);

    try {
        final Process child = Runtime.getRuntime().exec(commandToExecute);

        final InputStream inputStream = child.getInputStream();
        readAndCloseStream(inputStream, false);

        final InputStream errorStream = child.getErrorStream();
        readAndCloseStream(errorStream, true);

        // prevent leaking file descriptors, close stream
        try {
            child.getOutputStream().close();
        } catch (final IOException ioe) {
            mavenPlugin.getLog().warn("Unable to close stream. " + ioe);
        }

        // check return value
        // 0 means a normal program termination
        final int exitValue = child.exitValue();
        if (exitValue != 0) {
            throw new RuntimeException("Executing command failed. Exit code: " + exitValue);
        }

    } catch (final IOException e) {
        throw new RuntimeException(e);
    }
}

知道为什么会这样，以及如何让maven正确解释源命令？

Maven似乎在Linux下截断了SQL import / misinterpret参数
