Java 通过gradle写入xlsx

我正在用selenium编写测试。我编写了一个testrunner，将测试结果写入xlsx文件。 问题是，这只适用于eclipse！ 如果我通过'gradle'运行2个或更多的TestClass，那么只有第一个类执行器会纠正testprotocol，在第一个类抛出异常之后，每个类都会遇到异常。结果是，只有第一个测试类结果被写入协议

问题不在任何testclass或testrunner中，因为在使用.csv文件时一切都正常。现在，换成xlsx后，我不再和gradle一起工作了

希望有人能帮忙

这是代码。它在每个测试类中都被调用。writeHead、writeData方法等正在用数据填充工作表。抛出的异常是方法：setCellValue

private void writeTableHead(Sheet sheet) {

    setCellValue(7, 0, "*******************************");
    // print versionline

    setCellValue(8, 0, "Version");
    int cellCount = 4;
    for (TestRun runTriple : summary.getTestRuns()) {
        setCellValue(8, cellCount, runTriple.version);
        setStyle(8, cellCount, styles.get("borderThin"));
        sheet.setColumnWidth(cellCount, 2500);
        cellCount++;
    }
    setCellValue(9, 0, "Build");
    cellCount = 4;
    for (TestRun runTriple : summary.getTestRuns()) {
        setCellValue(9, cellCount, runTriple.build);
        setStyle(9, cellCount, styles.get("borderThin"));
        cellCount++;
    }
    setCellValue(10, 0, "Package");
    setCellValue(10, 1, "Class");
    setCellValue(10, 2, "Name");
    setCellValue(10, 3, "Type");
    cellCount = 4;
    for (TestRun runTriple : summary.getTestRuns()) {
        setCellValue(10, cellCount, new SimpleDateFormat("dd.MM.yyyy").format(runTriple.date));
        setStyle(10, cellCount, styles.get("date"));
        cellCount++;
    }

}

private void writeHead(Sheet sheet) {
    double totalFailed = summary.getNumberOfFailedTests();
    double totalSkipped = summary.getNumberOfSkippedTests();
    double totalSucceeded = summary.getNumberOfSucceededTests();
    double totalNumberOfTests = summary.getNumberOfTests();
    double succeededPercent = totalSucceeded / totalNumberOfTests;
    double failedPercent = totalFailed / totalNumberOfTests;
    double skippedPercent = totalSkipped / totalNumberOfTests;

    setCellValue(0, 0, "TESTPROTOKOL");

    setCellValue(1, 0, "Archiv");
    setCellValue(1, 1, "Git repository");

    setCellValue(2, 0, "Anzahl Tests");
    setCellValue(2, 1, totalNumberOfTests);

    setCellValue(3, 0, "Erfolgreiche Tests");
    setCellValue(3, 1, totalSucceeded);
    setCellValue(3, 2, succeededPercent);

    setCellValue(4, 0, "Fehlgeschlagene Tests");
    setCellValue(4, 1, totalFailed);
    setCellValue(4, 2, failedPercent);

    setCellValue(5, 0, "Geskippte Tests");
    setCellValue(5, 1, totalSkipped);
    setCellValue(5, 2, skippedPercent);

}

private void setCellValue(int row, int column, String value) {
    Row tmpRow;
    if (sheet.getRow(row) == null) {
        tmpRow = sheet.createRow(row);
    } else {
        tmpRow = sheet.getRow(row);
    }
    tmpRow.createCell(column).setCellValue(value);
}



private void writeToFile() {

    try {

        // Write protocolHEAD
        writeHead(sheet);

        // Write tableHEAD
        writeTableHead(sheet);

        // print data
        writeData(sheet);
        formatSheet(sheet);

        FileOutputStream stream = new FileOutputStream(file);
        wb.write(stream);
        stream.flush();
        stream.close();

        System.out.println("Protocol written to " + file.getAbsolutePath());
    } catch (Exception e) {
        log.warning("error occured while writing protocol file: " + e.getClass().getCanonicalName() + ": " + e.getMessage());
        e.printStackTrace();
    }
}

主要问题是，gradle试图并行执行多个测试。因此，第一个测试开始写入文件，因此其他测试将阻止访问该文件。按顺序运行测试后，一切正常

看起来非常类似于您多次尝试执行写入操作。。。请分享代码…@Nikolay Lagutko:不一样。只有使用gradleTask运行测试时，问题才会出现。如果我手动运行，一切正常。所以我认为主要的问题是：gradleTask和通过eclipse手动运行的gradleTask之间有什么区别。
