Phantom syntax errors [message #892807]

Ever since upgrading to Juno, Eclipse is stopping me from building my project saying there are syntax errors(Where there are none)

For example, I just added this new line

System.out.println("Comm Client Created");

and am getting the following error on that line

Syntax error, insert ";" to complete Statement

As you can see, I clearly have a semicolon... I can right click the error in the "Problems" tab and hit delete to make the error go away and I can compile and run without any problems. I'm getting similar errors with closing curly brackets on any block.

I know it's not my code, I've been programming in C# for years and java syntax is almost identical. I can even cut and re-paste the offending line or block in place and the error will be gone.

Can you give a few more details? Like:

What package of Juno did you install?
Have you installed any additional plug-ins?

Where exactly is the error marked (red wiggle line)?
If there are several errors, what is the first error in the file?
Does the file contain any non-ascii characters?

I can confirm this problem. It happened today to me also in the following line:

g.drawCenteredText(String.format(context.getString(R.string.about_panel_count), panelCount), 400, 360, versionPaint);

It insists in that I must add a semicolon there, where it is yet.

As you, I could simply remove the errors for the Problems view and it compiled fine.

I am using the latest Android ADT with Eclipse. Anyway it seems not to be related with ADT but with Eclipse itself.

Eclipse Platform:
Version: 3.7.0
Build id: I20110613-1736

I am not 100% sure, but it seems like some errors were not clear when they should.

For example, you write an incomplete for loop and save, then you will get an error on for token or so. You continue editing til the for loop is completed, save again, but the error message persists even when it has been solved, and the only way to get rid of it is deleting it from the Problems view.

If you think these errors occur with just JDT and no ADT in the loop, please try to create a reproducable test case.

Note, that even if you "just edit Java code" if you have the ADT installed, their builder will kick in when you save. To ensure that ADT is not involved, please disable that builder (right click the project > Properties > Builders).

If the problem goes away when ADT builder is disabled, please report against the ADT.

best,
Stephan

Hi,

I do not know how plugins works, may be you are right and it is a problem with ADT. It is not crazy because I updated it yesterday just before the problems started.

I will try what you say later, since I was coming here just to put another case that has happen just a minute ago:

package com.marzoa.ruletafree;

import android.content.Context;

public class PanelUpdater {
private Context context;

public PanelUpdater (Context context) {
this.context = context;
}
}

I have written the line:

private Context context;

First as:

private context;

So I get an error. But I wrote it right as private Context context; and I still get an error shown ("- Syntax error on token "context", VariableDeclarator expected after this token") even when I have saved the file again many times.

As told before, if I remove the error message on "Problems", it is not shown again.

Regards,
