| # This file is meant to be included into a target to provide a rule |
| # to generate Java source files from templates that are processed |
| # through the host C pre-processor. |
| # |
| # To use this, create a gyp target with the following form: |
| # { |
| # 'target_name': 'android_net_java_constants', |
| # 'type': 'none', |
| # 'sources': [ |
| # 'net/android/NetError.template', |

| # 'template_deps': ['net/base/certificate_mime_type_list.h'], |
| # }, |
| # 'includes': [ '../build/android/java_cpp_template.gypi' ], |
| # }, |
| # |
| # The 'sources' entry should only list template file. The template file |
| # itself should use the 'ClassName.template' format, and will generate |
| # 'gen/templates/<package-name>/ClassName.java. The files which template |
| # dependents on and typically included by the template should be listed |
| # in template_deps variables. Any change to them will force a rebuild of |
| # the template, and hence of any source that depends on it. |
| # |

| # when building targets that depend on this one. |
