从Java调用时，Perl进程找不到命令svn

echo $PATH

export PATH=$PATH:/path/to/svn

ProcessBuilder pb = new ProcessBuilder("perl", "your_script.pl");
Map<String, String> env = pb.environment();
env.put("PATH", env.get("PATH") + ":/path/to/svn");
Process process = pb.start();

# 在Perl脚本中使用绝对路径
system('/absolute/path/to/svn update');

ls -l /path/to/svn

ProcessBuilder pb = new ProcessBuilder("perl", "your_script.pl");
Map<String, String> env = pb.environment();
env.put("PATH", "/usr/local/bin:/usr/bin:/bin:/path/to/svn");
Process process = pb.start();
