Eclipse插件开发:不鼓励访问:由于对所需库的限制,EclipseStarter类型无法访问

tes*_*ser 2 eclipse eclipse-pde eclipse-plugin eclipse-jdt

我知道"阻止访问"应该是什么意思:你正在使用内部库,不在公共API中的东西,而你根本就不应该使用它.

现在,据我所知,包"org.eclipse.osgi.util"中的类EclipseStarter是公共API的一部分.我引用:

This package specifies API to start the platform.
Clients may use the EclipseStarter loader class to start the platform. 
The EclipseStarter class is the only defined API in this package.

EclipseStarter类的详细信息页面指出:

Special startup class for the Eclipse Platform. This class cannot be instantiated; 
all functionality is provided by static methods.

Note that the fields on this class are not API.

我读过:方法是开放的吗？

我的代码:

import org.eclipse.core.runtime.adaptor.EclipseStarter;

这个已经发出警告"不鼓励访问:由于对所需库[path-to-eclipse]\plugins\org.eclipse.osgi_3.7.2.v20120110-1415.jar的限制,EclipseStarter类型无法访问"

我使用该类的代码:

try {
    EclipseStarter.shutdown();
    EclipseStarter.startup(null, null);
} catch (Exception e) {
    e.printStackTrace();
}

警告:不鼓励访问:由于对所需库[path-to-eclipse]\plugins\org.eclipse.osgi_3.7.2.v20120110-1415.jar的限制,EclipseStarter类型无法访问

警告:不鼓励访问:由于对所需库[path-to-eclipse]\plugins\org.eclipse.osgi_3.7.2.v20120110-1415.jar的限制,无法访问EclipseStarter类型的shutdown()方法

警告:不鼓励访问:由于对所需库[path-to-eclipse]\plugins\org.eclipse.osgi_3.7.2.v20120110-1415的限制,无法访问EclipseStarter类型的方法startup(String [],Runnable).罐

我知道,我现在正在使用null值调用启动方法,这可能不起作用,但我现在只是编写代码 - 还没有运行.我不喜欢这些警告.要么我完全错了(而且EclipseStarter不公开),我配置中的某些东西都是错的......

我尝试调整类路径,以便插件依赖性首先出现(在内部JRE之前),但这也不起作用.这些警告所讨论的库是在依赖项中,而不是在我的JRE中.我不知道还能尝试什么.

无论哪种方式,底线我实际上是在寻找一种以编程方式重启Eclipse的好方法.插件代码首先安装一些额外的插件(没有警告,用户也必须接受所有这些插件的许可协议),然后应该重新启动.我一直在使用PlatformUI.getWorkbench().restart();,但是在重新启动日志时会出现错误("事件循环"或其他内容).

谁能指出我正确的方向？谢谢!

编辑:PlatformUI.getWorkbench().restart()给出的错误如下:

编辑2:我很确定上面的错误发生了,因为这段代码是错误的.我如何编写performFinish代码以便不会发生该错误？用asyncExec？

@Override
public final boolean performFinish() {
    if (getContainer().getCurrentPage().equals(myLastPage)) {
        PlatformUI.getWorkbench().restart();
        return true;
    } else {
        return false;
    }

这个回复50次,很明显,当Widget被处理掉时,他仍然试图执行某些操作.

这是新performFinish代码:

@Override
public final boolean performFinish() {
    if (getContainer().getCurrentPage().equals(myLastPage)) {
        Display.getDefault().asyncExec(new Runnable() {
            public void run() {
                PlatformUI.getWorkbench().restart();
            }
        });
        return true;
    } else {
        return false;
    }
}

只是为了完成:现在一切正常.还有另一个类(一个帮助器类),在访问它之前我没有检查Text-widget是否被处理掉了.一旦解决了这一切,它就会成为一种魅力.感谢greg-449!

PlatformUI.getWorkbench().restart();是重启的正确方法(除非您运行纯'e4'RCP).您需要查看导致事件循环错误的原因.

包含的包EclipseStarter标记在org.eclipse.osgi MANIFEST.MFwith中x-friends="org.eclipse.core.runtime",这意味着它仅供其使用org.eclipse.core.runtime,所有其他插件将获得不鼓励的访问警告.
