Проверьте этот ответ тоже.
Вот метод подтверждения для StAX и других зависимостей, которые не содержат pom.properties
просто manifest.mf
.Возможно, стоило бы кэшировать экземпляры Properties
, если есть много вызовов assertDependencyByMetaInf
.
@Test
public void testStaxDependency() throws Exception {
assertDependencyByMetaInf("StAX", "1.0.1");
}
private void assertDependencyByMetaInf(final String specTitle,
final String expectedSpecVersion) throws IOException {
final ClassLoader cl = this.getClass().getClassLoader();
final String resourcePath = "META-INF/MANIFEST.MF";
final Enumeration<URL> resources = cl.getResources(resourcePath);
boolean found = false;
while (resources.hasMoreElements()) {
final URL url = resources.nextElement();
final InputStream metaInfStream = url.openStream();
final Properties metaInf = new Properties();
metaInf.load(metaInfStream);
final String metaInfSpecTitle =
metaInf.getProperty("Specification-Title");
if (!specTitle.equals(metaInfSpecTitle)) {
continue;
}
final String specVersion =
metaInf.getProperty("Specification-Version");
assertEquals("version mismatch for " + specTitle,
expectedSpecVersion, specVersion);
found = true;
}
assertTrue("missing dependency: " + specTitle, found);
}
