java.lang.IllegalArgumentException:由于无效的密钥而无法初始化

Question

我收到加密异常.

我在跑

• OS X 10.11
• Java 1.8
• Groovy版本:2.4.4
• Gradle 2.3-20141027185330 + 0000;
• JAVA_HOME = /图书馆/的Java/JavaVirtualMachines/jdk1.8.0_05.jdk /内容/首页

我将Oracle JCE Policy jar安装到我的$ JAVA_HOME/lib/security目录中:

$ ls -l $JAVA_HOME/lib/security
total 16
-rw-r--r--@ 1 root  wheel  2487 Oct  9 17:21 US_export_policy.jar
-rw-r--r--@ 1 root  wheel  2500 Oct  9 17:21 local_policy.jar

这是例外:

Answer 1

这个问题最常见的原因是/ lib/security没有安装Java密码术扩展(JCE)无限强度管辖权策略文件

从这里下载Java 7 jar

从这里下载Java 8 jar

按照自述文件,你应该启动并运行

Answer 2

可能发生这种情况的其他原因：

• 您在项目中没有使用 JDK 而不是 JRE
• 您没有将策略 jar 放在正确的文件夹中（基本上是 JDK/jre/lib/security - 请参阅自述文件）。
