Question

我是Maven的新手。我必须在我的项目中使用类sun.security.tools.JarSigner。我正在尝试添加tools.jar作为依赖。我继续Maven's FAQ，来自stackowerflow和google的其他文章，但没有一些积极的结果。

我的NetBean可以＆＃34;看到＆＃34; JarSigner类机智pom beloow。

我可以无错误地编译项目或发出警告但我无法运行它。

在mvn exec:java -Dexec.mainClass="com.mycompany.Main"

Answer 1

将<systemPath>${java.home}/../lib/tools.jar</systemPath>更改为<systemPath>${java.home}/lib/tools.jar</systemPath>。

顺便问一下，您是否知道您正在通过JDK版本进行分离？ default-tools.jar个人资料将被激活为jdk 1.6及以下（根据java.vendor属性），因为我看到你正在使用jdk 7，我想这是多余的。

Answer 2

我的解决方案：我从$finalJSON = []; $finalJSON["items"] = []; echo json_encode($finalJSON);中提取包{"items":[]}，并将此编译的源复制到sun.security.tools文件夹。在编译阶段，我将编译后的类复制到tools.jar。

src

Maven：JAVA_HOME / lib / tools.jar作为依赖
