    /**
     * Required. A comma-separated list of paths, relative to `Environment`, of
     * fields to update.
     * For example, to set the version of scikit-learn to install in the
     * environment to 0.19.0 and to remove an existing installation of
     * numpy, the `updateMask` parameter would include the following two
     * `paths` values: "config.softwareConfig.pypiPackages.scikit-learn" and
     * "config.softwareConfig.pypiPackages.numpy". The included patch
     * environment would specify the scikit-learn version as follows:
     *     {
     *       "config":{
     *         "softwareConfig":{
     *           "pypiPackages":{
     *             "scikit-learn":"==0.19.0"
     *           }
     *         }
     *       }
     *     }
     * Note that in the above example, any existing PyPI packages
     * other than scikit-learn and numpy will be unaffected.
     * Only one update type may be included in a single request's `updateMask`.
     * For example, one cannot update both the PyPI packages and
     * labels in the same request. However, it is possible to update multiple
     * members of a map field simultaneously in the same request. For example,
     * to set the labels "label1" and "label2" while clearing "label3" (assuming
     * it already exists), one can
     * provide the paths "labels.label1", "labels.label2", and "labels.label3"
     * and populate the patch environment as follows:
     *     {
     *       "labels":{
     *         "label1":"new-label1-value"
     *         "label2":"new-label2-value"
     *       }
     *     }
     * Note that in the above example, any existing labels that are not
     * included in the `updateMask` will be unaffected.
     * It is also possible to replace an entire map field by providing the
     * map field's path in the `updateMask`. The new value of the field will
     * be that which is provided in the patch environment. For example, to
     * delete all pre-existing user-specified PyPI packages and
     * install botocore at version 1.7.14, the `updateMask` would contain
     * the path "config.softwareConfig.pypiPackages", and
     * the patch environment would be the following:
     *     {
     *       "config":{
     *         "softwareConfig":{
     *           "pypiPackages":{
     *             "botocore":"==1.7.14"
     *           }
     *         }
     *       }
     *     }
     * **Note:** Only the following fields can be updated:
     * * `config.softwareConfig.pypiPackages`
     *     * Replace all custom custom PyPI packages. If a replacement
     *       package map is not included in `environment`, all custom
     *       PyPI packages are cleared. It is an error to provide both
     *       this mask and a mask specifying an individual package.
     * * `config.softwareConfig.pypiPackages.`packagename
     *     * Update the custom PyPI package *packagename*,
     *       preserving other packages. To delete the package, include it in
     *       `updateMask`, and omit the mapping for it in
     *       `environment.config.softwareConfig.pypiPackages`. It is an error
     *       to provide both a mask of this form and the
     *       `config.softwareConfig.pypiPackages` mask.
     * * `labels`
     *     * Replace all environment labels. If a replacement labels map is not
     *       included in `environment`, all labels are cleared. It is an error to
     *       provide both this mask and a mask specifying one or more individual
     *       labels.
     * * `labels.`labelName
     *     * Set the label named *labelName*, while preserving other
     *       labels. To delete the label, include it in `updateMask` and omit its
     *       mapping in `environment.labels`. It is an error to provide both a
     *       mask of this form and the `labels` mask.
     * * `config.nodeCount`
     *     * Horizontally scale the number of nodes in the environment. An integer
     *       greater than or equal to 3 must be provided in the `config.nodeCount`
     *       field. Supported for Cloud Composer environments in versions
     *       composer-1.*.*-airflow-*.*.*.
     * * `config.webServerNetworkAccessControl`
     *     * Replace the environment's current `WebServerNetworkAccessControl`.
     * * `config.softwareConfig.airflowConfigOverrides`
     *     * Replace all Apache Airflow config overrides. If a replacement config
     *       overrides map is not included in `environment`, all config overrides
     *       are cleared.
     *       It is an error to provide both this mask and a mask specifying one or
     *       more individual config overrides.

     *       It is an error to provide both a mask of this form and the

     *       variables are cleared.

     * It is also possible to replace an entire map field by providing the
     * map field's path in the `updateMask`. The new value of the field will

     * Required. A comma-separated list of paths, relative to `Environment`, of
     * fields to update.
     * For example, to set the version of scikit-learn to install in the
     * environment to 0.19.0 and to remove an existing installation of
     * numpy, the `updateMask` parameter would include the following two
     * `paths` values: "config.softwareConfig.pypiPackages.scikit-learn" and
     * "config.softwareConfig.pypiPackages.numpy". The included patch
     * environment would specify the scikit-learn version as follows:

     * other than scikit-learn and numpy will be unaffected.

     * For example, one cannot update both the PyPI packages and
     * labels in the same request. However, it is possible to update multiple

     * to set the labels "label1" and "label2" while clearing "label3" (assuming
