我正在尝试使用 Proguard 4.8 混淆我在 java 7 中的项目。

这是我的 Maven 插件配置：

            <plugin>
            <groupId>com.pyx4me</groupId>
            <artifactId>proguard-maven-plugin</artifactId>
            <executions>
                <execution>
                    <phase>package</phase>
                    <goals>
                        <goal>proguard</goal>
                    </goals>
                </execution>
            </executions>
            <configuration>
                <proguardVersion>4.8</proguardVersion>
                <obfuscate>true</obfuscate>

                <options>
                    <option>-ignorewarnings</option>
                    <option>-dontshrink</option>
                    <option>-dontoptimize</option>
                    <option>-allowaccessmodification</option>
                    <option>-keep class !ua.com.sintez.exceptions.** { *; }</option>
                </options>
                <injar>${project.build.finalName}.jar</injar>
                <outjar>${project.build.finalName}-proguard.jar</outjar>
                <outputDirectory>${project.build.directory}</outputDirectory>
                <libs>
                    <lib>${java.home}/lib/rt.jar</lib>
                    <lib>${java.home}/lib/jsse.jar</lib>
                </libs>
                <addMavenDescriptor>false</addMavenDescriptor>
            </configuration>
            <dependencies>
                <dependency>
                    <groupId>net.sf.proguard</groupId>
                    <artifactId>proguard</artifactId>
                    <version>4.8</version>
                    <scope>runtime</scope>
                </dependency>
            </dependencies>
        </plugin>

我试图混淆只有一个包“ua.com.mycompany.exceptions”，看看它是否有效。该软件包不包含任何有关 JPA 的内容。persistence.xml 就在它的位置，所有实体都在那里。但是当我启动程序时，我收到以下错误：

        The collection of metamodel types is empty. Model classes may not have been found during entity search for Java SE and some Java EE container managed persistence units.<br/> 
java.lang.IllegalArgumentException: Unknown entity bean class: class ua.com.mycompany.entity.Currency, please verify that this class has been marked with the @Entity annotation.<br/> 
java.lang.IllegalArgumentException: An exception occurred while creating a query in EntityManager: Exception Description: Problem compiling [select count(p) from Product as p]. 
The abstract schema type 'Product' is unknown.

所以我有以下问题：

  1. 该错误的原因可能是什么？
  2. proguard配置错了吗？
  3. 我也收到了很多这样的：Note: duplicate definition of library class ...和许多这样的警告：Warning:net.sf.jasperreports.compilers.JavaScriptEvaluator: can't find referenced class org.mozilla.javascript.Context。
    可以吗，如果可以，我该如何抑制它？
