如何防止proguard修改我的方法中的字段名称？如何防止proguard修改我的方法中的字段
我知道我们可以使用-keep, -keepclassmembers ..等但这些似乎只保留成员名称而不是内部使用的变量。
这里发生了什么：
前：
private static URL getPluginImageURL(Object plugin, String name) throws Exception {
// try to work with 'plugin' as with OSGI BundleContext
try {
Class<?> BundleClass = Class.forName("org.osgi.framework.Bundle"); //$NON-NLS-1$
Class<?> BundleContextClass = Class.forName("org.osgi.framework.BundleContext"); //$NON-NLS-1$
if (BundleContextClass.isAssignableFrom(plugin.getClass())) {
Method getBundleMethod = BundleContextClass.getMethod("getBundle", new Class[0]); //$NON-NLS-1$
Object bundle = getBundleMethod.invoke(plugin, new Object[0]);
//
Class<?> PathClass = Class.forName("org.eclipse.core.runtime.Path"); //$NON-NLS-1$
Constructor<?> pathConstructor = PathClass.getConstructor(new Class[]{String.class});
Object path = pathConstructor.newInstance(new Object[]{name});
//
Class<?> IPathClass = Class.forName("org.eclipse.core.runtime.IPath"); //$NON-NLS-1$
Class<?> PlatformClass = Class.forName("org.eclipse.core.runtime.Platform"); //$NON-NLS-1$
Method findMethod = PlatformClass.getMethod("find", new Class[]{BundleClass, IPathClass}); //$NON-NLS-1$
return (URL) findMethod.invoke(null, new Object[]{bundle, path});
}
} catch (Throwable e) {
// Ignore any exceptions
}
// else work with 'plugin' as with usual Eclipse plugin
{
Class<?> PluginClass = Class.forName("org.eclipse.core.runtime.Plugin"); //$NON-NLS-1$
if (PluginClass.isAssignableFrom(plugin.getClass())) {
//
Class<?> PathClass = Class.forName("org.eclipse.core.runtime.Path"); //$NON-NLS-1$
Constructor<?> pathConstructor = PathClass.getConstructor(new Class[]{String.class});
Object path = pathConstructor.newInstance(new Object[]{name});
//
Class<?> IPathClass = Class.forName("org.eclipse.core.runtime.IPath"); //$NON-NLS-1$
Method findMethod = PluginClass.getMethod("find", new Class[]{IPathClass}); //$NON-NLS-1$
return (URL) findMethod.invoke(plugin, new Object[]{path});
}
}
return null;
}
proguard的经过：
private static URL getPluginImageURL(Object plugin, String name)
throws Exception
{
try
{
localClass1 = Class.forName("org.osgi.framework.Bundle");
localClass2 = Class.forName("org.osgi.framework.BundleContext");
if (localClass2.isAssignableFrom(plugin.getClass())) {
localObject1 = localClass2.getMethod("getBundle", new Class[0]);
localObject2 = ((Method)localObject1).invoke(plugin, new Object[0]);
localClass3 = Class.forName("org.eclipse.core.runtime.Path");
localObject3 = localClass3.getConstructor(new Class[] { String.class });
Object localObject4 = ((Constructor)localObject3).newInstance(new Object[] { name });
Class localClass4 = Class.forName("org.eclipse.core.runtime.IPath");
Class localClass5 = Class.forName("org.eclipse.core.runtime.Platform");
Method localMethod = localClass5.getMethod("find", new Class[] { localClass1, localClass4 });
return (URL)localMethod.invoke(null, new Object[] { localObject2, localObject4 });
}
}
catch (Throwable localThrowable)
{
Class localClass2;
Object localObject1;
Object localObject2;
Class localClass3;
Object localObject3;
Class localClass1 = Class.forName("org.eclipse.core.runtime.Plugin");
if (localClass1.isAssignableFrom(plugin.getClass()))
{
localClass2 = Class.forName("org.eclipse.core.runtime.Path");
localObject1 = localClass2.getConstructor(new Class[] { String.class });
localObject2 = ((Constructor)localObject1).newInstance(new Object[] { name });
localClass3 = Class.forName("org.eclipse.core.runtime.IPath");
localObject3 = localClass1.getMethod("find", new Class[] { localClass3 });
return (URL)((Method)localObject3).invoke(plugin, new Object[] { localObject2 });
}
}
return null;
}
注意如何localObject1和localObject2不再有类声明？这不会使代码在语法上不正确吗？
