Example 89 with ByteArrayOutputStream

use of org.apache.commons.io.output.ByteArrayOutputStream in project gradle by gradle.

the class PropertiesUtils method store.

/**
 * Writes {@link java.util.Properties} in a way that the results can be expected to be reproducible.

 * <p>There are a number of differences compared to {@link java.util.Properties#store(java.io.Writer, String)}:</p>
 * <ul>
 *     <li>no timestamp comment is generated at the beginning of the file</li>
 *     <li>the lines in the resulting files are separated by a pre-set separator instead of the system default line separator</li>
 *     <li>the properties are sorted alphabetically</li>
 * </ul>
 *
 * <p>Like with {@link java.util.Properties#store(java.io.OutputStream, String)}, Unicode characters are
 * escaped when using the default Latin-1 (ISO-8559-1) encoding.</p>
