错误:选项-Xbootclasspath/p:目标12不允许(Netbeans 11.0)
错误:选项-Xbootclasspath/p:目标12不允许(Netbeans 11.0)
提问于 2019-05-23 17:40:24
我正在将IDE升级到netbeans (11.0)和jdk (12.0)的最新版本。当我使用Ant Project创建一个简单的基本Web应用程序时，我无法编译它，因为输出显示以下错误消息：
错误:选项-Xbootclasspath/p:不允许，目标12构建失败(总时间:1秒)
显然，Ant脚本使用此选项，而jdk 12不允许此选项？但是如何解决这个问题呢？
编辑:这是使用选项-Xbootclasspath的部分(build-impl.xml)。这是netbeans生成的脚本。如果完全删除该选项，则编译成功，应用程序似乎可以工作

我刚刚注意到netbeans 11推荐使用JDK 8，而不是更新的版本。所以我要回到JDK 8..(“问题”已解决)。

要在JDK12上编译项目，只需在project.properties文件中将空值设置为endorsed.classpath=。

JDK9中删除了-Xbootclasspath和-Xbootclasspath/p：(前缀)。您仍然可以使用-Xbootclasspath/a:将内容附加到bootstrap类路径。
