如何将此证书安装到JRE CACERTS？

在进一步确认之前你已经找到正是给出这个错误的jre。很多时候，IDE使用与其捆绑的jre而不是系统jre。在我的情况下，我将所有的IDE指向我的系统Java安装。

1. 在你的jre bin文件夹内使用keytool.exe。
   
2. fire following命令将证书放在cacerts文件中

keytool -import -noprompt -trustcacerts -alias ALIASNAME -file

/PATH/TO/YOUR/DESKTOP/CertificateName.cer -keystore
/ PATH / TO / YOUR / JDK / jre / lib / security / cacerts -storepass changeit

现在您的问题已被解决！重新启动IDE并检查结果。

I tried to install the checkstyle-Plugin for my eclipse bundle Eclipse for Java Developers, by dragging the provided link from http://eclipse-cs.sourceforge.net/#!/ onto my Eclipse window.

Unfortunately this results in the following error:

An error occurred while collecting items to be installed
session context was:(profile=epp.package.java, phase=org.eclipse.equinox.internal.p2.engine.phases.Collect, operand=, action=).

Any idea how I might fix this?

Installing it using the Marketplace also did not work. It failed with:

解决方案

How to get Root Certificate?

1. Open Google Chrome and navigate to https://sourceforge.net/
2. Click on icon just besides your url. see following image.

3. Click on View Certificate.You can see hierarchy and select top most certificate in hierarchy
4. Confirm that certificate have ROOT word in its name.

HOW TO INSTALL THIS CERTIFICATE INTO JRE CACERTS?

Before you proceed further do confirm you had located exactly that jre which is giving this error. Many times IDE uses jre which is bundled with it not system jre. In my case I pointed all my IDE to my system Java installation.

1. use keytool.exe inside your jre bin folder.
2. fire following command to place your certificate inside cacerts file

keytool -import -noprompt -trustcacerts -alias ALIASNAME -file
/PATH/TO/YOUR/DESKTOP/CertificateName.cer -keystore /PATH/TO/YOUR/JDK/jre/lib/security/cacerts -storepass changeit
