为什么我不能让我的 Windows 10 计算机执行 Java ProcessBuilder？

Question

我在用Processbuilder执行Windows程序时遇到问题。下面的代码产生一个命令数组，如：

C:\Program Files\Gdal\bin\gdal\apps\gdalwarp.exe, -t_srs, EPSG:32633, -et, 1, -r, near, H:\GeoData\Raster\1M_WEF30JAN2020_WGS84LL_somlos_8.tif, H:\GeoData\Raster\result.tif

String [] cmd = {"C:\Program Files\Gdal\bin\gdal\apps\gdalwarp.exe",
"-t_srs",  "EPSG:" + txtEPSG.getText(), 
"-et", txtThreshold.getText().trim(),
"-r", cmbBoxResampl.getSelectedItem().toString(),
txtInFilename.getText(),
txtNewFilename.getText()
};
boolean r = Files.isExecutable(new File("C:\Program Files\Gdal\bin\gdal\apps\gdalwarp.exe").toPath());
java.lang.ProcessBuilder b = new java.lang.ProcessBuilder(cmd);
b.redirectError(ProcessBuilder.Redirect.INHERIT);
b.redirectInput(ProcessBuilder.Redirect.INHERIT);
Map<String,String> map = b.environment();
Process p = b.start();
int rc = p.waitFor();
if (p.exitValue() != 0) {
System.out.println(p.exitValue());
System.out.println("Command: " + cmd[0]);
InputStream errorStream = p.getErrorStream();
int c = 0;
while ((c = errorStream.read()) != -1) {
System.out.print((char)c);
}
}

当我调试java程序时，我可以看到gdalwarp.exe是可执行的，并且环境设置与我在cmd终端中执行gdalwarr.exe时相同。processBuilder似乎没有执行gdalwarp。我得到的退出代码是-103741511，应该是0或-1。errorStream是空的，我没有打印出来。

当我执行C:Program FilesGdalbingdalappsgdalwarp.exe -t_srs EPSG:32633 -et 1 -r near H:GeoDataRaster1M_WEF30JAN2020_WGS84LL_somlos_8.tif H:GeoDataRasterresult.tif在cmd终端中，我得到了有意义的输出和结果文件：H:\GeoData\Raster\result.tif.

我尝试过使用和不使用gdalwarp.exe的路径，但它只有在cmd终端中才能工作。有什么想法吗？

当我使用ProcessBuilder执行cmd.exe时，我会得到有意义的输出。

-更新----

当我在程序中添加退出代码、isExecutable、env.variables的打印输出时，我得到的是：

Command: C:Program FilesGdal_321bingdalappsgdalwarp.exe, -t_srs, EPSG:32633, -et, 1, -r, near, C:Temp1M_WEF30JAN2020_WGS84LL_somlos_8_overview.tif, C:Temp1M_WEF30JAN2020_8_overview.tif

C:Program FilesGdal_321bingdalappsgdalwarp.exe is exacutable

Exit value:-1073741511

Answer 1

在使用调用p.waitFor()之前，请尝试读取输出

List<String> results = readOutput(process.getInputStream());

并可能将这些结果打印出来进行检查。

Answer 2

如果我添加工作方向，它就可以工作！

ProcessBuilder b = new java.lang.ProcessBuilder(cmd);
File f = new File("C:\Program Files\Gdal_321\bin\gdal\apps");
b.directory(f);
Process p = b.start();
