使用Java 9和Java 10在Eclipse上从Tomcat删除java.endorsed.dirs [英] removing java.endorsed.dirs from Tomcat on Eclipse with Java 9 and Java 10

问题描述

我在IDE中将Eclipse 4.7.3a与Tomcat 9.0.4结合使用.我从Java 8升级到Java10.我将JAVA_HOME更改为指向JDK 10安装.我进入Eclipse，并创建了一个新的JDK，它安装了指向Java 10 JDK的JRE，然后选择了它.我重建了项目，并尝试启动我拥有的Tomcat服务器.它说:

I'm using Eclipse 4.7.3a with Tomcat 9.0.4 in the IDE. I upgraded from Java 8 to Java 10. I changed my JAVA_HOME to point to the JDK 10 installation. I went into Eclipse and created a new JDK installed JRE pointing at the Java 10 JDK, and selected it. I rebuilt my project, and tried to start the Tomcat server I had. It said:

-Djava.endorsed.dirs=C:\bin\tomcat\endorsed is not supported. Endorsed standards and standalone APIs
in modular form will be supported via the concept of upgradeable modules.

我四处寻找，发现在Eclipse的Tomcat启动配置中，参数"选项卡下有以下VM参数:

I poked around and found that in the Tomcat launch configuration in Eclipse, under the Arguments tab, there are the following VM arguments:

-Dcatalina.base="I:\work\.metadata\.plugins\org.eclipse.wst.server.core\tmp1" -Dcatalina.home="C:\bin\tomcat" -Dwtp.deploy="I:\work\.metadata\.plugins\org.eclipse.wst.server.core\tmp1\wtpwebapps" -Djava.endorsed.dirs="C:\bin\tomcat\endorsed"

我删除了最后一部分，-Djava.endorsed.dirs="C:\bin\tomcat\endorsed"，然后单击应用"，但所做的更改并未粘滞"；回到该对话框时，该值仍然存在，并且仍然无法运行Tomcat.

I removed the last part, -Djava.endorsed.dirs="C:\bin\tomcat\endorsed", and hit Apply, but the changes don't "stick"; when I come back to that dialog, the value is still there, and I still can't run Tomcat.

如何从Eclipse Tomcat配置中删除java.endorsed.dirs系统属性?

How can I removed the java.endorsed.dirs system property from the Eclipse Tomcat configuration?

更好的是，我该如何完全避免该问题? Eclipse和Tomcat还不支持Java 9+吗? Tomcat 9的较新版本是否可以解决该问题?我应该删除并重新添加Eclipse服务器吗?我该如何找到问题的根源?

Better yet, how can I avoid the problem altogether? Isn't Eclipse and Tomcat ready for Java 9+? Will a newer version of Tomcat 9 fix the problem? Should I remove and add back the Eclipse server? How can I get to the root of the problem?

推荐答案

我也有这个 WTP 插件更新到最新版本之前和之后的问题 .5)，甚至解决该问题的最新Eclipse(Oxygen.3a)也未包含.

I also have this problem before and but after updating WTP plugin to the latest version (3.9.5) which is not included even in the latest Eclipse (Oxygen.3a) to solve the problem.
