Usage

From source file:org.moe.designer.gradle.PropertiesUtil.java

public static void savePropertiesToFile(@NotNull Properties properties, @NotNull File filePath,
        @Nullable String comments) throws IOException {
    FileUtilRt.createParentDirs(filePath);

    try {
        //noinspection IOResourceOpenedButNotSafelyClosed
        out = new FileOutputStream(filePath);
        // Note that we don't write the properties files in UTF-8; this will *not* write the
        // files with the default platform encoding; instead, it will write it using ISO-8859-1 and
        // \\u escaping syntax for other characters. This will work with older versions of the Gradle
        // plugin which does not read the .properties file with UTF-8 encoding. In the future when
        // nobody is using older (0.7.x) versions of the Gradle plugin anymore we can upgrade this
        properties.store(out, comments);
    } finally {
        Closeables.close(out, true);
