Examples with CommandResult com.google.devtools.build.lib.shell.CommandResult used on opensource projects

Example 1 with CommandResult

use of com.google.devtools.build.lib.shell.CommandResult in project bazel by bazelbuild.

the class AppleHostInfo method getSdkRoot.

/**
   * Returns the absolute root path of the target Apple SDK on the host system for a given
   * version of xcode (as defined by the given {@code developerDir}). This may spawn a
   * process and use the {@code /usr/bin/xcrun} binary to locate the target SDK. This uses a local
   * cache file under {@code bazel-out}, and will only spawn a new {@code xcrun} process in the case
   * of a cache miss.
   *
   * @param execRoot the execution root path, used to locate the cache file
   * @param developerDir the value of {@code DEVELOPER_DIR} for the target version of xcode
   * @param sdkVersion the sdk version, for example, "9.1"
   * @param appleSdkPlatform the sdk platform, for example, "iPhoneOS"
   * @param productName the product name
   * @throws UserExecException if there is an issue with obtaining the root from the spawned
   *     process, either because the SDK platform/version pair doesn't exist, or there was an
   *     unexpected issue finding or running the tool
