## default_cds

    File JavaRuntimeInfo.default_cds

Returns the JDK default CDS archive. May return `None`.

## files

    depset JavaRuntimeInfo.files

Returns the files in the Java runtime.

## hermetic_files

    depset JavaRuntimeInfo.hermetic_files

Returns the files in the Java runtime needed for hermetic deployments.

## hermetic_static_libs

    sequence JavaRuntimeInfo.hermetic_static_libs

Returns the JDK static libraries.

## java_executable_exec_path

    string JavaRuntimeInfo.java_executable_exec_path

Returns the execpath of the Java executable.

## java_executable_runfiles_path

    string JavaRuntimeInfo.java_executable_runfiles_path

Returns the path of the Java executable in runfiles trees. This should only be used when one needs to access the JVM during the execution of a binary or a test built by Bazel. In particular, when one needs to invoke the JVM during an action, java_executable_exec_path should be used instead.

## java_home

    string JavaRuntimeInfo.java_home

Returns the execpath of the root of the Java installation.

## java_home_runfiles_path

    string JavaRuntimeInfo.java_home_runfiles_path

Returns the path of the Java installation in runfiles trees. This should only be used when one needs to access the JDK during the execution of a binary or a test built by Bazel. In particular, when one needs the JDK during an action, java_home should be used instead.

## lib_ct_sym

    File JavaRuntimeInfo.lib_ct_sym

Returns the lib/ct.sym file. May return `None`.

## lib_modules

    File JavaRuntimeInfo.lib_modules

Returns the lib/modules file. May return `None`.

## to_json

    string JavaRuntimeInfo.to_json()

Deprecated. This API is deprecated and will be removed soon. Please do not depend on it. It is disabled with `---incompatible_struct_has_no_methods`. Use this flag to verify your code is compatible with its imminent removal.
Creates a JSON string from the struct parameter. This method only works if all struct elements (recursively) are strings, ints, booleans, other structs, a list of these types or a dictionary with string keys and values of these types. Quotes and new lines in strings are escaped. Examples:

    struct(key=123).to_json()
    # {"key":123}

    struct(key=True).to_json()
    # {"key":true}

    struct(key=[1, 2, 3]).to_json()
    # {"key":[1,2,3]}

    struct(key='text').to_json()
    # {"key":"text"}

    struct(key=struct(inner_key='text')).to_json()
    # {"key":{"inner_key":"text"}}

    struct(key=[struct(inner_key=1), struct(inner_key=2)]).to_json()
    # {"key":[{"inner_key":1},{"inner_key":2}]}

    struct(key=struct(inner_key=struct(inner_inner_key='text'))).to_json()
    # {"key":{"inner_key":{"inner_inner_key":"text"}}}

.

Deprecated: instead, use json.encode(x) or json.encode_indent(x), which work for values other than structs and do not pollute the struct field namespace.

## to_proto

    string JavaRuntimeInfo.to_proto()

Deprecated. This API is deprecated and will be removed soon. Please do not depend on it. It is disabled with `---incompatible_struct_has_no_methods`. Use this flag to verify your code is compatible with its imminent removal.
Creates a text message from the struct parameter. This method only works if all struct elements (recursively) are strings, ints, booleans, other structs or dicts or lists of these types. Quotes and new lines in strings are escaped. Struct keys are iterated in the sorted order. Examples:

    struct(key=123).to_proto()
    # key: 123

    struct(key=True).to_proto()
    # key: true

    struct(key=[1, 2, 3]).to_proto()
    # key: 1
    # key: 2
    # key: 3

    struct(key='text').to_proto()
    # key: "text"

    struct(key=struct(inner_key='text')).to_proto()
    # key {
    #   inner_key: "text"
    # }

    struct(key=[struct(inner_key=1), struct(inner_key=2)]).to_proto()
    # key {
    #   inner_key: 1
    # }
    # key {
    #   inner_key: 2
    # }

    struct(key=struct(inner_key=struct(inner_inner_key='text'))).to_proto()
    # key {
    #    inner_key {
    #     inner_inner_key: "text"
    #   }
    # }

    struct(foo={4: 3, 2: 1}).to_proto()
    # foo: {
    #   key: 4
    #   value: 3
    # }
    # foo: {
    #   key: 2
    #   value: 1
    # }

Deprecated: use proto.encode_text(x) instead.

## version

    int JavaRuntimeInfo.version

The Java feature version of the runtime. This is 0 if the version is unknown.
