I have an Eclipse project (Flex Builder) of which the actual files have changed location on the drive. When I start Eclipse I can see the project listed but there are no actual files listed. Right clicking the project and selecting properties will show me the old path where the files used to be stored but I can't change it.
How can I change the file location of an Eclipse project where it will look for the files after the project has been created?
This link shows how to edit the eclipse workspace metadata to update the project's location manually, useful if the location has already changed or you have a lot of projects to move and don't want to do several clicks and waits for each one: https://web.archive.org/web/20160421171614/http://www.joeflash.ca/blog/2008/11/moving-a-fb-workspace-update.html
I moved my default git repository folder and therefore had the same problem. I wrote my own Class to manage eclipse location and used it to change the location file.
File locationfile
= new File("<workspace>"
+"/.metadata/.plugins/org.eclipse.core.resources/.projects/"
+"<project>/"
+".location");
byte data[] = Files.readAllBytes(locationfile.toPath());
EclipseLocation eclipseLocation = new EclipseLocation(data);
eclipseLocation.changeUri("<new path to project>");
byte newData[] = eclipseLocation.getData();
Files.write(locationfile.toPath(),newData);
Here my EclipseLocation Class:
public class EclipseLocation {
private byte[] data;
private int length;
private String uri;
public EclipseLocation(byte[] data) {
init(data);
}
public String getUri() {
return uri;
}
public byte[] getData() {
return data;
}
private void init(byte[] data) {
this.data = data;
this.length = (data[16] * 256) + data[17];
this.uri = new String(data,18,length);
}
public void changeUri(String newUri) {
int newLength = newUri.length();
byte[] newdata = new byte[data.length + newLength - length];
int y = 0;
int x = 0;
//header
while(y < 16) newdata[y++] = data[x++];
//length
newdata[16] = (byte) (newLength / 256);
newdata[17] = (byte) (newLength % 256);
y += 2;
x += 2;
//Uri
for(int i = 0;i < newLength;i++)
{
newdata[y++] = (byte) newUri.charAt(i);
}
x += length;
//footer
while(y < newdata.length) newdata[y++] = data[x++];
if(y != newdata.length)
throw new IndexOutOfBoundsException();
if(x != data.length)
throw new IndexOutOfBoundsException();
init(newdata);
}
}
