用java调用rpmbuild 报错，同一条命令直接复制到终端却能运行

Question

用java调用rpmbuild 报错，同一条命令直接复制到终端却能运行。
命令如下：

rpmbuild --define "_topdir /var/lib/jenkins/workspace/compositor-build-CI/target/rpmbuild/compositor" --define "service_desc compositor" --define "service_name compositor" --define "service_release CI.last" -ba SPECS/rpmbuild.spec --clean --target i686-redhat-linux

java调用代码如下：

String rpmBuildScript = String.format("rpmbuild --define \"_topdir %s\" --define \"service_desc %s\" --define \"service_name %s\" --define \"service_release %s\" -ba SPECS/rpmbuild.spec --clean --target i686-redhat-linux", new File(privateRpmBuild).getAbsolutePath(), serviceName, serviceName, version);
getLog().info("RPM build command: " + rpmBuildScript);
Process exec = Runtime.getRuntime().exec(rpmBuildScript, null, new File(privateRpmBuild));
exec.waitFor();
BufferedReader in = new BufferedReader(new InputStreamReader(exec.getErrorStream()));
String line;
while ((line = in.readLine()) != null) {
    getLog().info(line);
}

错误输出：

[INFO] RPM build command: rpmbuild --define "_topdir /var/lib/jenkins/workspace/compositor-build-CI/target/rpmbuild/compositor" --define "service_desc compositor" --define "service_name compositor" --define "service_release CI.last" -ba SPECS/rpmbuild.spec --clean --target i686-redhat-linux

其中的"error: failed to stat /var/lib/jenkins/workspace/compositor-build-CI/target/rpmbuild/compositor": No such file or directory"，这条报错语句有点诡异，我直接用Jenkins用户进去能找到这个目录，并且复制rpmbuild命令并执行能生成正确的rpm文件。

附上rpmbuild.spec文件

悟了.

String[] command={"/bin/bash", "-c", rpmBuildScript};
Process exec = Runtime.getRuntime().exec(command, null, new File(privateRpmBuild));
